AT&T Uverse Lied about the service and Overbilled me after cancelation Carol Stream Illinoise

In December 2019 I signed up for AT&T Uverse. Being in the middle of football season, I asked the lady that I was speaking with 3 times and was assured each time that they had NFL Redzone. I set up the service and when Sunday comes, I cannot find it on the TV anywhere. At that point, I call in for assistance finding it and find out that I was lied to, they do not even offer NFL Redzone. I took a couple of months and figured out that I wanted to switch to Spectrum. At that point, I called AT&T, told the young man on the phone that I intended to cancel my service and wanted to pay everything that I owed to that point.

I paid what I owed and immediately turned took all of the equipment to the UPS store and turned it in. All of this information should be on a recorded call that can be heard. The lies I was told in the beginning, the call of me canceling my service, and the equipment turn-in has been verified by the people I have spoken to since, plus, there has been absolutely no activity on my account since the cancelation and equipment turn in. At that point, I had switched to Spectrum and had full service with them.  

Being on the phone and juggled back and forth with several people in July, they finally canceled my service but were billing me in excess of $800 for services that were not supposed to be charged. The last person I was on the phone with assured me that everything would be taken care of. The only thing that was done was they adjusted the bill $200 and sent me a new bill. Since then I have spent countless hours with countless people explaining my situation and being told that the people I was talking to could not help me and that they would send it up and someone would contact me. No one ever has. I did my due diligence and canceled my service, paid what I owed, and turned the equipment in. I can't imagine how any company could in good conscience continue to not help me get this corrected. Now, they have turned it into a collection agency and now I have another issue on my hands. 

This bill is not owed, it is due to the incompetence of the employees at AT&T. Honestly, this is the worst experience I have ever had in my life with a company, From the lies that I was told in the beginning, to the way they have continued to bill me after cancelation, and the lack of contact with anyone that could help me resolve this after being told that someone would contact me time and time again. I do not owe this bill and I would like it to be resolved by adjusting it to $0.00
