So SORRY this happened to your Mother. These people that do this prey not only on the elderly they will try it with anyone they can. The sad thing is that they may try it again since she fell for it once they may figure they can get more money from her again so be careful.
About a month ago I had a phone call..blocked number..answered anyway...male voice said...Hi Grandma...well red flag...I DO have grandsons BUT they are 13-8 & 5 and the voice certainly was older. I said who is this....he says Michael...another red flag as I don't have a Michael grandson....I said Hello...Hello..he says bad connection Hello Hello and the phone went dead. I feel like it was one of those scams...could of been wrong number but if that is the case why didn't he say sorry wrong number?
You just have to be so careful now days and that is sad.
