Another ex-AT&T customer deals with bill shock: “Dishekie” reports he disconnected AT&T service in March after the phone company failed to get his small company’s Voice over IP phone system functioning properly. “I was reassured my contract was nullified because the VoIP phones never worked,” says the customer. Wrong. AT&T claims the bill is for fraudulent calls placed over the company’s hacked phone system. AT&T has not been willing to resolve the charges, which continue month after month, but hasn’t turned the customer over to collections either, leaving “Dishekie” opening one eye-popping bill after another. He took his case to Reddit, which seems to have finally gotten the attention of a vice president of finances at AT&T who may have a solution, or not.
