My mother had two salesman sell her some windows for way more than she had to spend and actually needed. I did not find out until after the 3 day federal law for cancellation. The company rep was very rude to me and told me that older people do not like family helping on these decisions. I told him I think that is what the company wants. Is there any law that requires a co-signature of a witness if the buyer is over a specific age. My mother has memory loss and did not even remember everything she bought.
