Complaint Review: Direct TV

I signed up as a bundle with Century Link. I was supposed to get a promotional deal for 1 year. It lasted 6 months and the bill doubled. Then when I was having trouble paying the bill, after my husband lost his job. They refused to work with me and change my package to a less expensive one. When I cancelled my contract, they started telling me that they were going to charge my credit card for a list of fees I never agreed to. I told the gal I was talking to that they were not authorized to do that. She kept going on and on about the fees etc. I hung up, called my bank and cancelled my credit card. Then called Direct TV back and cancelled my contract. They proceeded to call me several times a day for 3 months after the cancellation. I had 9 months to go on the contract and my bill is over $500, when it should only be around $250. I returned the equipment so there shouldn't be a charge for that. I've not seen it. I've not seen a final bill either. I've been sent to a collection agency CBD Group who is now calling me several times a day including Sundays and before 8 am and after 9pm.
