Trying to switch from Now Mobile to xfinity mobile

I am beyond frustrated. we were sold NOW Mobile by a rep over the phone without realizing what service we were paying for (1.5 years ago). it’s worked fine enough but for the past year we’ve had limited access to our accounts online and we’re having major issues getting support through their ONLY METHOD OF CONTACT - chat. We have since decided to switch to a different carrier altogether. We successfully ported our 1 of our 4 lines. The other three lines kept giving the other carrier issues by saying the account info didn’t match. We have reached out to support via corporate store, phone calls and chat. We’ve been told different reason for the issues each time. One rep suggested we switch from NOW mobile to regular xfinity to make the port out easier… that also hasn’t worked bc they “cant find the remaining lines”. We’ve been told our issue will be resolved and it never is. This is now 1.5 weeks of no resolution. I’m now being told that we had 2 NOW mobile accounts - one with the single line (that was ported out), the other account with the remaining 3 lines… the issue is now I have NO WAY to access the other NOW mobile account. when I go to log in it now says I don’t have NOW mobile services. most recently I was told told NOW mobile will not be able to transfer our phone numbers and we will need to get NEW NUMBERS. absolutely not. please please has someone dealt with something similar and were you able to fix it??? im desperate and our numbers are being held hostage at freaking NOW mobile and NO ONE CAN HELP!!
