Failed port in poor customer service no resolution

I transferred my mobile number to xfinity from total wireless over 3 weeks ago. I have data on xfinity's network but no ability to send or receive texts or calls. Nobody in store at any location nor via chat or phone has been able to resolve this issue. Multiple physical Sims and esims have been swapped in and out of my device in attemp to get this resolved but the results are always the same. Under settings my device's sim status shows 'xfinity mobile' and 'number unknown'. I'm told this is because there was a glitch when transferring my number over from total wireless. Everyone i talk to goes through the same fruitless scripted troubleshooting steps that continue to resolve nothing. Filed complaint with FCC and ensuing response also resolved nothing. Worst company I've ever done business with. Other networks tell me I need to resolve my port in with xfinity before attempting to port out to a more reputable and competent carrier. Resolution seems unlikely and situation is hopeless. I'm hardly the only one experiencing these issues. Xfinity cannot seem to handle the most basic of tasks.
