Valued long time customer

I was offered a promotion Sept 2025 to receive a free phone along with upgrades to my account. I was not told I had to pay off the phone but instead pay for the service for up to two years and then could either return the phone or keep it and add a plan. Upon numerous calls with long wait times and even a promos to talk to the supervisor, which did not occur, I am left repeating this situation. All I wanted to do was return the phone I was sent for a trial period. I now have to pay off the rest of the phone. I was not helped but just talked at until I said I would just pay it off since no one would help and couldn’t reach a supervisor. After years of being with xfinity using all services, I am debating leaving this company all together. I’m very disappointed.
