I am visiting my Aunt in care as I am the only one able. It doesn't matter when I go, she is wearing someone else's clothes, her bottom dentures don't get cleaned even though I provided them with what she needs. She only wears bottom denture. The place reeks of urine from the door you enter the place. There is nothing for residents to do but literally sit in same chair entire day
If you do not hold POA, I'm afraid you have no right to call such a meeting. Whoever does hold that title needs to advocate for your aunt.
Good luck to you.
