T-Mobile - UPS lost phone. Nobody is doing anything

Hi all, Recently updated my old phone and ordered a new iPhone18 Pro thru T-Mobile. They shipped the phone and it should've arrived about 8 days ago. Tracking number says that it got to a warehouse in Orlando FL and that's where the mystery starts. No updates for 7 days. I called UPS and they will not help, because T-Mobile needs to call them and or file a claim. T-Mobile is useless and will not do anything about it. I tried escalating the issue and the manager basically told me that I am out of luck. That there is nothing they can do. They will NOT cancel the order, they will NOT send me a new phone and THAT lost phone is still on my account. I cannot file a claim with UPS, I cannot put a trace. Do you guys know what else can be done? TIA
