My husband's cell phone is the same problem. We have had the phone for 2 yrs and still getting calls for Colby. Found out he is the nephew of my DD's SIL. I have asked and asked that he tell people he has a differant number. We had a guy call last year on Halloween and cuss Glen out and called him names and told him he was going to come and beat him up. My sweet? DH in a wheelchair mind you tells him to come on I''m not going anywhere! Glen grew up rough and fighting was a way of life. So he has the family motto down pat - Nobody but nobody walks over me no matter how big you are! LOL The guy called an hour later and I answered it. He just kept screaming he was tired of us taking his newspaper and we would regret it ...on and on..... So Glen sat and waited to see if someone would show up!! Noone did. We decided the guy was drunk and nowhere near where we live. We know all our neighbors well and it wasn't any of them!
Yes this cell phone thing is really annoying!!
