mobile number porting

Since November 11 and officially November 18 when the port request for my residential LANDLINE was sent to Century Link Lumen to release to Xfinity Mobile - I have been on chat, customer service and escalation teams and Tier 3 Support and then finally the store with no success. Every representative tells me they will help me and all they do is submit a support request. I never get to speak with the department responsible for porting my #. The last conversation on 12/17 I called Lumen porting department with Xfinity Tier 3 online AND THE XFINITY REPRESENTATIVE ARGUED WITH LUMEN AND SAID THEY NEED TO RELEASE THE #.  Lumen has been telling me and Xfinity that the port request was approved and pending since 11/18. She refreshed it and say it would be available for one more day and expired in 30 days.  Xfinity called me back and said they were sending a NEW REQUEST even though Century Link just told us that the port request was approved and how to access it. Your representatives in chat suggested I go to the store and I did so today - ONCE AGAIN all they did was put in a support request stating that the 12/17 support request was closed and that is why nothing was done. AND I HAVE TO WAIT A WEEK before I can check on status.!  I have paid over $120 upfront for a phone that doesn't work without internet AND have paid 2 months of mobile phone. I requested a refund for the past 2 months of payments and for paying Century Link to keep my phone # active! Is there no other way to solve this without filing a complaint with the Philadelphia, PA corporate office and share the incompetence I have received and I'm a new customer - not so good even with free one year mobile service (not really as I don't have a working phone) and 5 year price guarantee!
