Unlock Motorola 5g Ace

Have been trying over a week to unlock my Motorola phone that I purchased from Xfinity. Hours spent listening to empty promises and even lies about getting phone unlocked from Xfinity agents. Supervisors are no help either. I'm told to wait 24-48 hours for an unlock code but they keep sending the same non-working code on 4 different times! Are you kidding me? . The code sent simply does not work despite all efforts including a complete phone reset. Does anyone have a suggestion?
