centry link\Direct tv continue to want money and state i owe when i do not.

I bundled with centrylink and Direct tv for Internet and tv service when I moved to Bailey in september 2019. When I signed up for the bundle I was told my bill would be about $98.43. + tax. I over looked a payment and was late with that payment. I did pay it in full in December 2019. I have proof of all payments made to centry link because that is who sent me the bill. I continued to get cancleation notices do to non payment. when I call centry link because that is where my bill comes form they explained that direct tv bills centry link and centry link pays direct tv what they ask for then send me the bill.

Every month I was calling asking why I was getting another disconect notice. Every time centrylink would blame direct tv for the fees. When I call direct tv they say it was because full payment was not made. I made that full payment 3 times. from December 2019 to April 2020 I payed 1,166.54 to centry link for the bills I was told I owed. By my calulations 98+ tax should be closer to $500 not $1,000. I decided to cancle diect tv march 2020.

  I payed the early termination fee of 280.00 and returned there equipement the very next day. I thought I was done with Direct tv and know I get a notice that they sent me to collections and want $360 more .  I do not owe them.   I was sent a email about a law suit against direct tv but decided I was done with them and did not want to deal with it. Now that I got this letter I want in on this law suit I done being ripped off by direct tv. please help me. Thank you
