Phone porting issues

I am pretty frustrated. I just typed out my whole issue and then it said issue - and deleted my whole post before I could submit it. 

Anyway I have been trying to port a iPhone 11 from T-Mobile to Xfinity and been getting a ton of errors that have stopped us from porting her phone number over. The first being that another port was pending and we needed to resolve that. This is the first time we tried porting anything. Second we got ahold of “the expert supervisor” in customer service and he said we need permission from T-Mobile. So we spend forever on the phone with T-Mobile trying to get permission but they kept saying as long as we have the porting pin then the authorization is taken care of. Then back to the first issue earlier.

Needless to say, I’ve been on the phone and in store for way too much time over the last 2 days. And I am seeing no light at the end of the tunnel. Customer service has no idea how to help- neither do the online chat people. And my in store reps have no idea either. I have no idea who to ask.

would love to get this resolved soon. If not we will need to move to another carrier.
