I was worried about my mother answering the phone and changing her bank account to a better one the bank recommended. This mucked up all the automatic payments. I had to go to the bank and use power of attorney to fix up the mess.
We then got her an answering machine and said not answer the phone and to let whoever is ringing give a number and you can call back your friends and let us listen to any you do not know.
It has worked out a lot better.
All her friends and relatives know the arrangement and it works well.
There have been a lot of hang up calls when we visit so she is missing a lot of cold calling. Also as she is in her 90’s she is not tempted to rush to answer the phone.
One call she had on the answering machine was from “the taxation office” saying she had a refund.
I said no way would the taxation department be ringing to give you a refund..
