How can I stop a sibling from refusing to abide by a POA and overrides the POA's decisions?

No one lives in the city my mom is at now—they didn’t visit mom at the 1st facility hardly ever or on a regular basis nor did they visit with her prior to dementia much before going to the assisted living home. I was with mom everyday at the facility before covid then during covid about every 2/3 days at her window to talk with her on my cell phone. I took care of her prior to dementia as she was a diabetic, and had several health issues. I was with her everyday prior to going to facility due to her age and health needs—she is now 95. I cooked her meals and made sure she ate, did her laundry, took to dr appts, took care of meds, took on trips, brought her to my house if weather was bad and in case power went out so she would still be warm as I am on the hospital grid and if power goes out, it’s back on in about 10-20 minutes, take her out to eat, basically did everything by myself. I do live closer to the facility she’s in now but the one she was in was 5 miles from me. One sister lives in another state and the other lives further away than I do. My sisters were always on to the staff and causing problems for that facility and even reported them to health Dept. I was told by that facility they had had enough..they were not able to satisfy my sister’s any longer or able to needs moms needs the way they wanted them met. They got tired of their mess. They even disrupted other residents and families that were at the facility. They wouldn’t take her dr while at that facility nor before going to facility and one never really came to the hospital when she was taken to ER...the other only came for a limited time and would leave. I was there every time and stayed until released to go back to the facility or home prior to the facility. They told me that mom wasn’t going to control their life and if I let her that was me. I didn’t feel she was controlling my life...I just wanted mom taken care of properly then and still do and have always felt that way... Even with dementia mom ask me where are my sisters. Out of 5 days being at this new place, I’ve been there 3 days...I call her if I don’t go then sometimes even if I do go I’ll talk with her during the day. With me working, the distance away now and now gas, I won’t be able to get there everyday like I’d like to do. I still do her laundry, get meds, take to doctors, pay her bills- done this for over 20 years basically as my dad’s been dead 20 years. I still get supplies she needs even tho she’s at facilities. I helped my mom with dad when he was sick...I’m an accountant and she said since I’d taken care of her and her financial needs all these years and this was what I did for a living, she said I had the knowledge to do the same thing for her even when she couldn’t do for for self... I was outside the door in a waiting area and heard her tell the attorney my sisters were not the for her at that time and had nothing to do with her or came around now when she was doing her legal documents so she didn’t want them doing it when and if she got to where she couldn’t herself. She hardly had visitors before going to facility nor the one she was at and with this one being further for her brothers and sisters now, I doubt they will every visit as it’s in a very busy area of town and they don’t drive much at all and haven’t for a while. They live further away from her than I do.

She has been declared imcompetent....

Thank you. I have tried to contact elderlaw attorneys & each one says the don’t get involved in family disputes. Something has got to be done as their actions now have gotten my mom thrown out of one facility & another rescinded their bed offer due to an email my sister sent to that facility. I’ve asked to see that email & got basically the same reply from them as the attorney, we don’t want to get involved in a family dispute so we are refusing to send you that email. I feel there must be something in that email that could possibly be defamation of character but can’t prove it. I do know my sisters have lied about things even said mom doesn’t want to go to the best facility which she has never said-that director did tell me that. In fact I can prove it. What else that may be in the email, I have no idea. I was told by an attorney to send this particular facility that rescinded the bed my POA documents & a HIPAA form requesting all the info they have but have yet to get a response. Basically my sisters have now gotten my mom thrown out of 2 facilities & the only one that will take her is about 32+ miles from me and takes about 40-45 minutes to get to it & could take longer in rush hours. With me being the POA it breaks my heart to know as of yet they refuse to stop harassing me or listening to me when I say no or this is the way things are going to be. Truthfully my mom will suffer as this new facility has no doctor and only 1 RN on 1st shift 8 hrs a day for the entire place then on call if needed & med techs on shifts with a resident assistant on 2nd & 3rd shifts. The facility I wanted & that rescinded the bed has a doctor on staff & on call 24/7-365; RN’s 24/7-365 as well as LPNs and CNA’s 24/7-365. It is 18 miles from me and takes about 20 to 22 minutes to get to. At this “new” current faculty they have all kind of charges-extra fees for every time someone enters her room, brings a plate of food-meal in a divided styrofoam plate with no tray & such; I have to supply every medical supply as well as personal items while the one that rescinded mom is all inclusive and has a flat fee. She could stay at the facility I wanted her at 6 months over the only one that accepted her & that cost would be for a 4 month stay. I have to supply all medical supplies & personal items. I pointed out the facility I wanted mom at is a 5star facility with the health dept & Medicare and ranks 4th in the entire state & has not had a single COVID case whatsoever while the other has had deaths and quite a few cases is about 3stars. My sisters ignore everything I said about moving her possessions and moved her furniture & all her items from the facility she was at ignoring me as to the time we would met to transfer furniture & such as well as mom. Mom’s items were taken out of the one that discharged her without my knowledge & they took her items to the now only facility that offered her a bed. Items are missing & I’ve asked where were they & get “oh, I’ve got them & they refuse to give those to me. The day of the move my mom cried and begged me to take her with me but the dr says she needs 24/7 care to be available due to her health issues and dementia. It breaks my heart to know how they have done; thus far have gotten away with it...I’ve even told them what the POA says-gave them a copy even & they tell me we are mom’s children as well & have a right to be part of the decision making. I continue to remind them they aren’t a part of the legal document nor does it say I have to include or tell them anything regarding mom. I have the Durable Power of Attorney, Financial POA & Health care directive & such. They refuse to respect mom’s wishes in every circumstance. I don’t know what to do nor have I yet found an attorney that will assist me in letting them know they are not abiding by a legal document. No one wants to get involved & it makes me so sick and upset-mom will suffer in the end with lack of care & financially.

The facility has the POA as do siblings - the siblings have even told them I was POA that’s as far as their acknowledgment goes. Everyones ignores what’s on the documents. No matter what I say or show them, it seems I’m invisible to everyone. I know how serious these are and what they say and have told them all they need to read them— they all have copies but I suppose they’ve taken the typing off the paper.
