Direct TV / ATT ATT / Direct TV promised to pay off $300 to my previous Service provider and never did. Cedar Park TX

ATT called me on or about Nov. 2016 and said that i needed to renew my contract. Then they said that they were in joint with Direct Tv and they could offer a better tv and internet boundle. I told Att that I had just renewed my Tv service. They said that they would pay off the tv provider that I had. I told them that I was fine with what I had, but they insisted and in fact the boundle was great, but I told them that I would need to pay the current provider between $300 to $350 to cancel service because I just had renewed. The customer service rep. said that they would pay off the $300 or $350 so I could get the ATT/direct tv boundle. 

Keep in mind, all of," this conversation is being monitored and recorded for training purposes' ..... So I went with the deal and If I can recall, I only received $85 dll from Direct TV. I called Direct tv, ATT and always gave me the run-around. Finally in 2017 I called ATT and direct tv to cancel service.  So now I was stuct with two bills, $350 from my previous provider and now direct tv $300 for early cancellation fee. Direct tv did not comply with what they agreed and also has a derogatory on my credit history.  Like I said before all of this conversation I had with att and direct tv was recorded. Hum.....
