Xfinity porting process is horrendous

I'm trying to port over from Sprint (now T-Mobile) to Xfinity and this whole process has been an absolute nightmare. In one day alone I've spent more than 12 hours on the phone trying to get this to go through. Numerous times I've been told it was all set, only for the time I was told to come and go with no change, leaving me sitting in another 45+ minute queue.

At one point an Xfinity agent said we needed to call in Sprint (even after I explained that what they were seeing was a red herring) and then after getting Sprint on the line they hung on me leaving me to talk with Sprint who told me what I already knew: everything is all set and approved on their end. Of course the only thing I could do at that point was hang up and wait in Xfinity's queue again.

Full timeline of events:

* Submitted porting request online, chose "Sprint" and entered the transfer PIN I was given from the old account holder. I'm coming from a family plan and I don't have direct access to the old account.

* The website said a glitch occurred and I had to call in.

* I called Xfinity and was told that the account and transfer PIN I provided were correct but the number was deactivated on the Sprint side (despite it being the number I was calling from).

* I called Sprint and they told me the number was active and that the PIN was wrong. I contacted to owner of the plan and got a new PIN.

* I called Xfinity and asked to change the PIN. They resubmitted the request with the new PIN but said the number was still not active. They also confirmed the request was going to Sprint.

* The agent called Sprint and there was a conference call. Apparently neither PIN I had been given was correct, but that didn't actually matter since on the backend the request was being sent to MetroPCS instead of Sprint which is why it was saying the number wasn't active.

* Got the Sprint account holder on the conference call and had Sprint directly release the transfer PIN to Xfinity to ensure there was no confusion. A member of Sprint's advanced porting team was added to the call and they had to submit a manual porting request and override the SPID to Sprint's SPID (6664) to make it actually go to the correct place. Was told to wait 15 minutes, reboot the phone and it should be all set.

* Waited 4 hours (rebooting occasionally), still no change.

* Called Xfinity back. Tried to explain the situation to the agent but it seemed the agent wasn't hearing a word I was saying as all they would do is tell me the issue was because my number wasn't active on Sprint. They started another conference call with Sprint and then hung up as soon as a Sprint agent was on the line. Sprint once again told me my number was active and they had a record of the porting request from the previous call and that it was already approved on their end. All I can do is call Xfinity back.

* Got a hold of Xfinity customer retention team hoping maybe they could get me to someone who could get me assistance from some some form of escalations to avoid another round through tier 1 support. Ultimately was told there is no path to escalations without going through tier 1 support each time (pretty much what I expected). Ultimately was transferred back to tier 1 support.

* More waiting on hold and again I had to go through the process of the tier 1 support agent resubmitting the request only to be told my number wasn't active wasn't active (because of the system apparently is routing Sprint requests to Metro). They escalated to the advanced porting team.

* Once escalated to the advanced porting team they confirmed the request from the first conference call was in but hadn't gone through because it was scheduled to be processed at 11:59pm that night. Was told I just had to wait for that time and it'd go through and all would be set.

* The time I was told the port would go through came and went, plus another 12 hours and still seemingly 0 movement. I wrote everything up to this point while waiting on hold again to talk to a tier 1 support agent.

* After getting connected, got escalated again. Advanced porting agent confirmed again the request should have gone through yesterday but was now just showing as "delayed" with no further info. They said they would put the request through manually. Once again their request was "delayed" with no specific reason given. Was told this was now being escalated to tier 3 and to expect it go go through in 3-6 hours.
* That was 4 days ago, and still zero developments. Haven't had time since then to spend another 2 hours on hold/dealing with tier 1, just to talk to someone with some visibility on the matter. Of course, it seems like even when I do eventually get through to someone who can see the manual requests they just tell me to wait 3 hours which inevitably pass with 0 movement.

Is there anything I can do to help move things along so I can actually start making use of my phone? This has been one of the worst experiences I've had with a company and it's brought all the negative feelings I had towards Comcast back stronger than ever after what I felt was years of making strides on the customer satisfaction side of things (minus needing to go through an automated troubleshooter that has never once solved anything to get assistance for internet issues). Now to rub salt in the wound Xfinity is sending me automated notifications telling me "you really should activate your new phone and start making use of your new service because we're gonna be charging you regardless".
