T-mobile bricked my home internet gateway, then UPS lost the return, now T-mobile is charging me $236 for it

This kind of non-return fee for Home Internet devices is happening to me now. I am in the same situation with more frustration. The only difference is that T Mobile is now asking $370 for a modem I have used for years and $0.59 late charge.

The modem was returned on February 2nd, 2023 and the tracking number provided by UPS is showing that the device was delivered to their warehouse in  Fort Worth-TX on February 6th, 2023 at 7:49 am. I have the receipt from the UPS drop-off location. The tracking number is showing a clear itinerary to their warehouse in TX (that matches the shipping label provided by T Mobile). T Mobile provided the shipping label and all costs on them but do they have insurance with UPS? I don't know but they should claim their investment on the shipping.

Somebody in their warehouse is not doing his job.

They are currently menacing to cancel my mobile service if payment is not made. I think I need help from BBB also.

Contact BBB and FCC. File a complaint if they do not do anything. Had issue with another internet provider and let them know I going to contact fcc and it got fixed quickly.  You can also ask for their retention department. If they have one , they have more power to fix things. Other customer service people are usually outsourced reps and are limited.
