I'm very concerned about my father in law, who is border line Alzheimer's, but still managing to live at home with some support from various quarters.
I was at his house recently doing some work in the garden, when a cold caller rang trying to sell something. They got short shrift from me, but it struck me that an elderly person like him would be very vulnerable to this sort of sales approach. Also, once committed to buying some useless solar panels or similar, he would forget about it and it would be impossible to trace.
Is there a way of registering somewhere so he doesn't get this type of call?
