Incorrectly sent to collections by Xfinity mobile

First off. I was an Xfinity customer for Internet services for over 15 years. I say was because I will never and I mean NEVER do business with comcast again. I will use dialup before I revert back to these crooks. I enquired online about getting mobile services from Comcast because I was a current internet customer and figured it would be beneficial to bundle my internet and mobile services together to get a better deal. That was my first mistake. After enquiring I realized Comcast was not cheaper than most of the competition even after the bundle so I decided not to take the mobile services with them. Never thought anything of it because I never signed up never put a sim card in a phone. Never made a call never did anything with anything. A few months go by and I receive notice from credit collections services that I owe money for Comcast Xfinity mobile services. Immediately picked up the phone called Comcast and explained the situation. They apologized and stated they would remove this from collections and clear the balance because I should not have been charged and they said" not to worry it will not appear on my credit report because it will be cleared up with credit collections services immediately"

I was calm and figured this was a mistake and they will take care of it. That was my Second mistake. A month goes by and I receive notification that Comcast has placed this debt on my credit. To make things worse this was at a time when I was applying for a mortgage. I called Comcast furious and was told for a second time this would be removed from my credit report. This is when I shifted into panic mode and started calling Comcast repeatedly for days on end on hold for hours at a time getting transferred to every rep and there mama and everytime it was..... " Not to worry this will be taken care of" this has been going on for over a year now and it still is on my report and weekly I call Comcast and get the same runaround and eventual "not to worry this will be taken care of". I have audio recordings of Comcast saying the debt is not valid and should be removed from my credit profile. I have tried calling credit collection services and they tell me call Comcast. Comcast now tells me the debt is not valid and has been removed from there system and yet credit collections services still claims Comcast has not informed them of this. I am tired of being just a number. I have expressed my disdain and the fact that because of Comcast and this single collection on my account I was unable to get a mortgage. A typical person in our society would just pay the 350 dollar debt they tacked on just to make life easier but I refuse it is the principal. Once again I have never used Comcast mobile services never signed up for services never used a phone never put a sim card in a phone never even recieved a bill from Xfinity mobile prior to being sent a collections letter. I paid my xfinity internet bill religiously I was in the app monthly and never saw any indication of a mobile account being activated or any money owed in my online portal. This needs to be rectified immediately I am at my wits end. This is how Comcast treats there customers they do not care they do not have your best interest at heart and they will blatantly lie to u just to get you off the phone. Since they will not do anything to actually help here and they don't seem to take ruining my credit seriously i am at the point where I have no other option aside from litigation because I am a man of principle and will NEVER pay for something I never asked for just to feed the machine. This needs to stop. I know it's a lot to ask but..... I need a Comcast representative with some common sense and decency to contact asap to have this situation rectified. You have ruined over 15 years of good will with myself over 350 dollars which is just sad. I just want this off my credit report so I can go along my merry way believe me I never want to have to contact Xfinity write a long post and waste countless hours of my time explaining my story over and over again. I need this taken immediately but the damage is done so I have nothing to lose at this point.
