I have been receiving calls from AT&T for 5 months about a bill. I do not have service with AT&T. Someone gave them my cell phone number as a back up number for a cell phone services. Now they call me every time this person does not pay his bill. I have called every month and complained. They claim they can not look up the information because of some privacy act. They refuse to remove my number from their system. They told me to put my number on the do not call list. I did and they are still calling me. They will call up to 5 times a day. The longer the person is not paying his bill the more phone calls I get. read full review »
