Ridiculous Customer Service

I have spent enumerable hours on the chat trying to resolve the multiple issues I've had with Xfinity in the past 2 years. The multiple service visits each with conflicting information from the techs, who are also frustrated with the corporate [Edited: "Profanity"].  I just spent an hour on the chat with Aniket, trying to simply get a replacement box for one of my tvs.  She attempted 2x to upsell me on a new internet plan, after multiple refusals she agreed to replace the box.  Then she argued with me about shipping it to me.  She finally agreed, sent a consent including the internet plan that I had refused, she tried to slip it by me… 

Again I said I just wanted the [Edited: "Profanity"] box, and it was another 10 minutes to get an additional consent, for adding a new TV to my plan.  Was this what I asked for?  No, it was not.  I hesitate to agree to billing changes, due to the fact that I canceled a subscription a year and a half ago and continued to be billed for it, to the tune of $300+. They couldn’t credit all back at once for some reason, and after arguing for over 2 hours about it, I agreed to them reducing my bill a small amount until I was fully compensated.  Which will take an eternity.  Needless to say I do not trust their book keeping.  

Ultimately she said I could just go to the store, and wanted to set it up for me.  Which I declined .  God knows how long that would have taken.  I am hoping I can call the store, request an exchange, go in and pick it up.  But I doubt it.
