Xfinity failure on my account with no resolution! Make it difficult to get ahold of corporate office!

Huge issue here! Jan 22 - Feb 21 of 2024 i had 3 lines on my account and everything was working perfectly. The next month Feb 22 - Mar 21 of 2024 they removed one of my lines(0172) and the insurance from my account completely BUT the phone line(0172) stayed ACTIVE THE WHOLE TIME until i added a new line(1961) in July 22 - Aug 21 of 2024. We found out AT THIS TIME that the line(0172) they deactivated from my account should have never been deactivated because i never authorized it and i didn't even know it was deactivated because i was STILL USING THE PHONE WITH THAT PHONE NUMBER(0172) from March of 2024 to August of 2024 without interruption of service at all and i also had my account on autopay so i didn't pay attention to a bill decrease. Moving forward, Xfinity realized they made a mistake so they added my phone line(0172) BACK TO MY ACCOUNT in September BUT... for some reason did NOT reactivate my insurance i had before they deactivated my phone FOR NO REASON. They told me they were fixing the account and i would start paying for my service on the line(0172) from August moving forward. GREAT i thought... Now come to February of 2025, the WIFI antenna on my S22 Ultra phone(0172) stops working so i try to file a claim with the insurance I THOUGHT I HAD AND SHOULD HAVE NEVER BEEN CANCELED BACK IN FEB OF 2024 and they tell me i did not have insurance during August of 2024 to February of 2025 WHICH IS CORRECT but i told them that they only reason i did not have insurance was because of THEIR MISTAKE TO BEGIN WITH... Moving forward, they will not do anything about replacing my S22 Ultra AT ALL and it FORCED ME TO GO PURCHASE THE S25 ULTRA FROM THE STORE IMMEDIATELY because i needed a phone NOW! Whoever the rep was that deactivated my line(0172) back in Feb of 2024 should be held accountable for his/her mistake. And then whoever the rep was in August of 2025 that added my line(0172) back to the account and did not make me aware of the fact that he wasn't adding the insurance back to the account should be held accountable as well. As of right now, me...the customer is taking the hit with an unusable phone (s22 ultra) because of the incompetance of two Xfinity employees and Xfinity themselves are not taking accountability for messing up my account to begin with.... Ridiculous!!! Please someone explain to me as to why I'm being punished for their failures?!?! [Edited: "All Caps"]
