URGENT: 2FA Lockout - Mobile Number Trapped in Lost FedEx Activation Loop. Front line support 'specialists' refuse to fix

FedEx lost my replacement device. My main phone number is now stuck in an internal 'Pending Activation' loop on that lost phone's IMEI. Phone support keeps trying to issue a 2-week ticket, but I am entirely locked out of my critical accounts due to two-factor verification. I need a Digital Care Expert to manually purge the stuck shipment activation flag and push an eSIM of my original number to my current device immediately. I have been on vacation abroad for the past two weeks and did not even know FedEx lost my shipment until the middle of last week while I was away. I can not afford to go without my original number which I've had for YEARS and is tied to all of my most critical 2fa accounts. Resolution needed ASAP. The Xfinity store representative neglected to add the global travel pass from my original line to my temporary line even though I told him I'd be abroad and to add it just in case this exact situation occurred, he neglected to do so and I am now being erroneously charged $500 in roaming fee's for barely a gigabyte of roaming data. This is a serious issue but the most pressing is that I need my old phone number back. This is of the utmost importance and I expect it to be solved by the end of the day or I will be forced to take more drastic actions.
