Hi AZ, I may have had a similar experience, maybe you can help me to understand.
I got a new phone w/ new #, soon after I began recieving calls from unknown ppl wanting to know why I was calling them and leaving not so nice msgs regarding an unpaid bill. I spoke w/ several and told them it was not me, I was just me, I finally got the service provider to change my # after I rec'd a not so nice msg from Nascar wanting to know what I wanted, I saved msg for my provider so they could document. I was told that happens for what ever reason....The company would call and leave a msg, it would show my phone number so they would call me...It was a mess. Is this somewhat what you are talking about? TIA ETA correct spelling
