WORST CUSTOMER SERVICE EXPERIENCE AS A CUSTOMER OF 7 YEARS

I HAVE BEEN A CUSTOMER WITH XFINITY SINCE 2018 AND I CAN SAY THAT THIS BY FAR (2025) HAS BEEN THE WORST CUSTOMER EXPERIENCE I HAVE HAD WITH XFINITY. ON BOTH TV/INTERNET AND MOBILE SERVICES. BUT I WILL FOCUS ON THE MOBILE SIDE FOR NOW. I HAVE HAD INSURANCE ON MY PHONE FOR YEARS. I HAVE PAID MY DEDUCTIBLE. IT IS DECEMBER 5TH AND I FILED A CLAIM ON NOVEMBER 29TH. THE PHONE DIDNT EVEN COME UNTIL DECEMBER 2ND AND EVEN UPON RECEIVING IT--IT WAS DEFECTIVE!!!! AND SO I SENT THE DEFECTIVE ONE BACK AND THEY ASSURED ME THAT ONCE I MAILED IT TO THEM THEY WOULD SHIP ME A NEW PHONE---I CAN TRACK THE PHONE THROUGH USPS ON MY END BUT THEY CLAIM THEY CANT TRACK IT...HOW????? THIS IS THE MOST FRUSTRATING AND ANNOYING CUSTOMER SERVICE EXPERIENCE EVER. XFINITY MESSED UP BY DOING 3RD PARTY OVERSEAS CUSTOMER SERVICE...ITS AWFUL!!! I CANT EVEN ACCESS THINGS ON MY PHONE BECAUSE IM WAITING IN LIMBO FOR A PHONE..ITS RIDICULOUS!!!
