Complaint Review: DIRECTV - DIRECTV

I have been a directv customer for 7+ years , I have had problems with their movers connection in the past so I decided to not keep their services when I moved again.I called directv last week to cancell my service , and told their (non) customer service rep to send me an itemized final bill so I could pay it and be done.She said ok , then on 2-22-10 directv charged my credit card without my permission forcing my account to be over drawn , which will have additional charges by my bank for.I called directv to find out why and instructed them to put my money back and give me a bill , they stated when I entered the agreement I was authorizing them to store and method of payment on their end and letting them use it at will.When I signed a contract I didnt have a debit card , inface I paid my start up cost with a western union charge , infact I got this debit card after I had the movers connection , so I don't know how they get away with this sleazy process , nor stay in business, it violates the fair billing act guidelines.
