Verizon unfair billing practices

For about two years I have held TV (Fios) and internet service with Verizon. Because of a promotion offering a reduced rate on digital phone I briefly signed up for a phone service with them as well. When they failed to bill me as the representative described I cancelled my services (phone first, later the Internet and TV) with them and elected to go to another provider.

Since I cancelled these services I continue to receive bills from them (mostly new phone charges). In fact, the month after I cancelled my phone service I received a bill from them for twice the cost of my old phone service. These charges were new charges appearing despite my having cancelled the service. I have called multiple times and discussed the issue with them many times. Each time I am told it will be taken care of but each time it is not and I receive letters indicating that my bill is in default. This may have been even affected my credit rating. However, I don't feel I should have to pay them for services I never received. Specifically, I shouldn�t have to pay them for services after I have cancelled the service. I would also like them to retract any negative reports to the credit agencies that this may have caused.

The account number is ***********. I have spoken with them on the phone many times (at least three times between 5/1 and 5/23, the original cancel order was number 745216951 made on or near 5/1). My most recent conversation with them was with a Mrs Poffman ticket number 885712. She was very helpful and I was told all the phone charges which were billed after my cancellation were to be removed, instead they simply added more charges despite my not having any service from verizon at this time. I am frustrated and tiered of talking with them. I also feel that each time the representative tries to help but then someone or something in their system prevents this from occurring and instead bills me for a greater fee.

I believe I need outside help to have this resolved fairly. I am more than happy to pay them for the services provided but not for ones after I my requested cancellation date. Please help me find a fair solution to this billing problem.

Thank you for your time and effort.
