Directv Charging for early termination when I never had a contract Atlanta, Ga Nationwide

I signed up for a bundle cable package through CenturyLink and was told that the cable would be connected through Directv but it was all part of the same package deal.  I sign up for a no contract with CenturyLink but for some reason they could not get the phone sevice hooked up but in the mean time the Directv man hooked up the cable.  In the mean time the phone company could not get the phone and wifi up and running so since I was still hooked up with my original provider I called and cancelled the CenturyLink account with no problem but could not get Directv turned off.  Since it was already hooked up I decided to keep it and I had not signed a contract with them plus it was at a low rate.  I called my original provider and had the phone and wifi with them but continued the cable service with Directv.   One month to a year of being with Diretv I received my bill and it was almost doubled what I was paying.  I called to correct the bill but was told that the price I was paying was a promotional price and that it was back at it's normal price.  When I called to cancel the account I was told that I could not cancel because I was on a two year contract and if I cancelled I would have two pay a huge early termination fee and return the equipment.  After attempts to influence me that I could not cancel the person on the line typed up the cancellation order.  I received the bill with a $200 cancellation fee (of which I'm not paying).  I payed the final bill less the $200 cancellation fee and sent their equipment.  Now I'm beginning to get their harrasement bill for the $200 early termination fee which I do not owe.  I will continue to return their bills to them and file any complaints I legally file against them if it takes forever.  As an American citizen I refuse to be taken advantage of by scammer just out to drain my pockets.  I want them to stop  asap sending bills to my house or calling my phone.
