Zip Code Incorrect When Porting out Number

I got a zip code incorrect error when I was trying to port my number to another carrier. 

My number was accidentally cancelled before porting out, and later it got reactivated. When I was trying to send a port request from another carrier after the line was activated, I always got an error message saying the "service zip code is incorrect". I have contacted Xfinity Assistant multiple times on the phone and through the chat box in the app. All they can do is confirm the zip code I entered should be correct or send out numerous urgent escalation tickets to the advanced team that I never heard back from. 

I have spent over a week and hours and hours on phone calls and support chat trying to solve the problems of reactivation and this zip code error, but I am still not able to get a resolution. 

Who else can I contact to try and solve this issue?
