Since then, I have called Verizon 4 times and have been told twice that my phone account is now cancelled and that the request has been backdated to 11/20., and not to worry about the online bill.
As of today, not only is the account apparently not cancelled, but the online bill has now doubled.
Why is it seemingly impossible to resolve this problem?
What else can I do?
