Get old xfinity land line phone number back! Its been 3 months of the runaround.

I started this new account in June because I was told we could get better pricing by cancelling our old account and starting as a new customer, but I was promised our landline phone number would transfer over. It has been 3 months and me talking to at least 5 representatives, spending hours on the phone, chat or in-store trying to get my phone number back. I even had it show up last month as processing and then went away again to a new phone number I do not want. The whole point of this was to keep the number. On top of that, I have had no dial tone on my phone number the whole time, so I'm paying every month for a service I'm not getting at all. Even yesterday I was told the issue was fixed after over an hour on chat and I still have seen no update in my account even to say a transfer is in progress. I want my old phone number back! This has been exhausting.
