Hello, I have just joined so very new here. My lovely mum has been diagnosed with early dementia. She is pretty ok, we just notice her repeat herself, and forget things, she is still able to run her home and cooks dinners for her grandchildren daily, she takes the bus to the shops gets off and on at the right stops, manages her money pretty well too. However, she is plagued by cold calls from energy companies to people trying to get hold of her shares. Yesterday I found her at home with a chap that was trying to sell her something to do with reducing the heating bill, this person also told her lots of sob stories about his dreadful life (none of which I believe) but my poor mum was worn out with this chap talking for over an hour and she, like me, really didn't know what he was trying to sell, I asked him for a business card and any product information, which of course he didn't have. I managed to get rid of him sharpish when I arrived. My question is how to help my mum just put the phone down and refuse to let these people into the house, I have no idea if he actually made an appointment or just turned up on the door, and poor mum can't remember. Any help, most appreciated.
