Cell Phone Problems? Want to Argue? How? Verizon wireless is charging way

[Vivid DVD]

too much!! Please Help? I recently signed a Verizon (NYSE: VZ) wireless contact for 5 lines. The day before I signed the contract I went and signed a one line contract to test the service. I liked the service so I went back the next day and told the sales clerk to CANCEL the one line contract and open a new one with 5 lines for my business name. So I spent about 5 hours of my saturday afternoon making sure everything was right. She said the monthly charges would be about $250.

Twenty days later I got a bill for $541! I went back to the store and argued with the manager for another 3 hours and she said she would solve the problem.
Apparantely the original sales clerk had not cancelled my original one line contract and had taken the phone without documenting it.

I went home thinking it was fixed.

Today,I got two bills, one for $363 and one for $59. I called Verizon and spent 4 hours talking to a manager to get this solved. She said she did.

Today i got a bill for $359.

How do I argue this? Not afraid to cancel.
