What an awful mess and disgraceful as well.
Is your Mother able to go to the bank if you went with her?
If you went with her for support she could explain to the manager if she needs to , what has been happening.
Is her pension paid into the bank?
This would let the care providers invoice you for their work and you could settle the bill.
I did this for my uncle who was 90 for many years.
It also saves cash being in the house, especially when the pension and other benefits are paid double at Bank holiday times.
You could arrange for your Mother to have a little available cash in her purse on a regular basis, providing that you live near enough to do this.
Has Mother made a will, if not she should certainly do that, and you could keep this in your safe, or let a solicitor keep it if that is what Mother wants.
Keep the texts as advised and yes go to the police as well.
Is Mother able to understand what has been happening?
If she is not sufficiently lucid you may be wise to get her a social worker who you can make aware of the position.
You may need ultimately to seek Power of attorney for your Mother's affairs--Help the Aged have fact sheets on this.
Has your Mother any expensive items e.g jewellery or whatever, if you can get Mother to put these in your safe keeping , it will stop your sister flogging them for cash.
Do not get into confrontation with your sister, personally or on the phone, this will not help you, and it may push your sister into violence as far as Mother is concerned.
Your priority is to protect Mother at all times from this nasty, wicked scumbag of a daughter, who is a thief as well.
Good Luck, please let us know how you get on if you can, we shall be thinking of you.
Be strong for your Mother.
