HUGE ISSUES with internet only plan

My roommate had handled internet and cancelled service this month. I made my own account, only wanting internet service and have been given the runaround by AI chatbots, reps oever chat, and reps on the phone (when I can even get someone on the phone).

They said that I would need an "install" because there was no history of service at our residence, a $100 appointment that is not necessary because my roommate still has their router and modem (bought separately from Xfinity). I had a tech agree over the phone to send me to the right department after paying a portion of the future bill. It was paid, I got my account ID shared that along with the Mac ID on the equipment with the next rep. That did not go smoothly but after talking with a number of chat reps my account and the equipment was active.

Yesterday I checked the account to see that the appointment still had not been cancelled (per many. MANY requests). A few chat reps later and it was cancelled.

Later that day I saw my account was no longer active. Reps said it was a "glitch" and I'd have to sign up again.

Reminder: I HAVE ALREADY PAID AND HAD ACTIVE SERVICE!

At this point I couldn't even get a real person on chat. The 1800xfinity number redirected me to chat no matter what options were chose. I found a way to schedule a callback and after a few tries it works. The rep leaves me on multiple holds but eventually gives me a slightly better deal on Internet service with a free phone line included.

After verifying all the details I agreed to the new plan. This time via link (previous time was vocally approved).

They said it would be confirmed and visible on the app in 15 minutes. 

Its been over 8 hours now and I can't get in contact with anyone to verify that my plan is active or changed. When I try to confirm it says to get a hold of or contact with "the account owner/holder". That's me! I own the account! I've put money into it!

Somebody needs to fix this before it becomes an issue with the FCC
