Unable to get phone number ported!

I switched to
Xfinity/Comcast August 2025. We requested our landline home phone
number [Edited: "Personal Information"] of 40 years be ported at that time. It is now
mid April 2026. I have spoken to service technicians over 40 times. I
have been put on hold multiple times for 2-4 hours. Each time I was
told the issue would escalate and be corrected shortly.
    I asked a technician to come and verify my set-up was correct. He
verified the modem was working correctly. He was unwilling to check
wires coming into the house or anything else. Everytime I asked about
connections he said I only do this. Anything else is corporate. He
would not help.
   I am writing this out of desperation!
