[Edited]! Xfinity Mobile Forced me to Pay for a Phone I Do Not Need

I have been an Xfinity's customer since Sep. 2021 for the internet service. In Sep. 2023, my internet bill increased $20/mo. and I reached out to customer service to figure out a possible solution. The customer service suggested me enroll in mobile plan, in which I will get a FREE PHONE, free monthly plan, and additional 30USD discount for my internet plan. I was not notified any information about 14-day return policy. 

One month passed. Discount for internet bill (Oct. 2023) did not pop up. I reached out to customer service again and they said I need to activate the phone. I brought my phone to a local Xfinity store (106 Main St, Weymouth, MA 02188). The agent kindly change a phone number for me, saying using the number generated via Google Voice is problematic. The store did not take the FREE PHONE as return, claiming it has passed 14-day return window, regardless of brand new phone packaged in the original box with sticker on. Meantime, the phone payment is recurring, a total of $200.

Ever since I was trapped in this non-ending ball-kicking game. The local store advised me to online customer service, while the online agent said only local store can take care of this. People kept convincing me keeping the phone, even though I made it clear at front that I do not need this phone at all. Now all of them kept saying I missed the 14-day return policy and over a month, while I have made many attempts over the past 3 weeks. How come a brand new phone was not accepted as return? Everyone said they were sorry after reading the transcript but still no one found a solution.

Lastly, I am really disappointed and frustrated on what Xfinity did to a loyal customer like me. This experience with mobile plan made me have no other option but to terminate all services I have with Xfinity.
