Router Issue, was sold something I DO NOT WANT-No one can figure out how to return it

Had a router issue starting on Saturday the August 2nd, 2025, finally had to deal with the Chat line to GET a router replacement. They said it would take until Wednesday to get one mailed OR I could go to a store. I chose store AND it took 4 stores to get the slightly better version that I already had been paying for years. In addition to that, the AI Chat decided that the best deal for me was to add the router, a new mobile phone line which OH goodie gives me an iPad.  I NEVER WANTED A MOBILE LINE OR AN IPAD! I received the iPad the following Thursday (7th) and i was getting phone calls NONSTOP from Xfinity to activate the service. I work and was completely behind due to internet. They finally caught me on Friday and I said I DO NOT WANT THE mobile line OR the iPad.  Turn it OFF.  So what did the guy do on the line, he said before he can turn it off he needs to activate it.  Its been a full blow time consuming NIGHTMARE! I STILL have the stupid unboxed iPad that after SEVEN hour long or more calls (EACH!) I have yet to get a return slip to send this iPad back....YET I can see the  iPad on a new mobile account you all set up.  I am FURUIOUS!  FUSIOUR that this so much reminds me of the Wells Fargo [Edited: "Language"] that happened years ago.....sell sell sell.  I need SOMEONE to get me a legitimate return slip to get this iPad back so I owe ZERO $ on my unwanted mobile account that I never wanted!
