about this is wouldn't the grandparents recognize their own grandkids voices? Of course, I only have two old enough to be asking for money, but I would know it wasn't them if someone else tried to do this to me. They would also get the third degree before any money went anywhere.
It's terrible though. I had a neighbor who was bilked out of $7,000 in a scam. No one wanted to believe me that this really happened until it came out in the newspaper.
