Question about my 88 year old mother is being sent home from rehab after breaking both hips.

I apologize in advance. This is a long post.
Advice is desperately needed, please.
I am my mother's full-time caregiver. She had a Silver Alert in 2017- and I moved in to help her.
My mother has Alzheimer's Disease with Sundowner's. On 3/19/2023 she fell at home- breaking the right hip and femoral bone. After hip replacement surgery- she was considered a "Fall Risk", because she continually tries to leave the bed to wander.
The hospital chose a rehab for her. I told the coordinator my mother needs a secure rehab, because she wanders.

The first day at rehab #1 she fell. No broken bones, luckily.
A week later - she fell again-breaking the left hip.
I learned about this when I called the desk to check on her at 6pm.
I asked what time my mother fell and I was told 11 a.m.
I learned later- the staff waited until 8pm to call 911- knowing from the x-ray that her left hip was now broken.
After hip replacement surgery for left hip- my mom was sent to a different rehab-she fell while there as well.
I spoke with rehab #2 nurse, who informed me they were not sent any instructions- from rehab #1 or hospital-regarding the right hip-and had not been rehabbing the right hip.
Next-
I received an angry voicemail last week from the head nurse.
She said "Your mother had a bottle of wine in her room, she was trying to open it and we took it from her. You need to get someone to come pick it up- it is locked in my office." I called her back and told her I am my mother's ONLY visitor- and I have not now-or ever- brought wine to her room. I had not even been there for a week- because I caught Covid while visiting her.
I learned they had "Happy Hour"- but the wine was not their brand.
I asked if anyone was in my mother's room. I asked if they had a video they could refer to- the answer was NO.
Finally- the nurse informs me that the staff was given wine baskets- which were scattered all over- on Mother's Day.
My mother took one.
They just called to tell me she will be discharged
Tuesday.
I feel they have not fully treated my mother for both hips. Yet they are releasing her.
I am overwhelmed and I need some advice please.
Thank you for reading this long post.
