We tried to upgrade a phone through Tmobile on one of our phones to trade in a phone on customer 2. January 2024. Tmobile coded the trade on customer 1's phone by mistake. They could not undo the order so we had to refuse shipment. It took 2 months for them to update our account because the refused phone was lost or stolen. Meanwhile they overcharged us for two months, including a monthly service charge for the new phone. They went through a process to render the lost refused phone unusable but in doing so, they coded my phone as the lost or stolen phone. March 2024. Thus I couldn't use my phone for a week. In the third month march 2024 they corrected our bill, and finally the mistake on coding my phone as lost or stolen was fixed, march 2024, only now they are charging us $50 more per month than before we ordered the upgraded phone. We consistently had a bill for $100 per month before all this happened. Now we have to haggle with them while they figure this mistake out. It appears they are charging in april us the monthly service charge for the phone we never got (after "fixing" our bill). I'm spending too much of my personal time talking to tmobile for these mistakes. My idea of a good time is not spending an evening talking to these folks about their mishaps. Time is a commodity they are using up without my consent. It's become a regular thing. We have decided to leave tmobile and file a complaint with the better business bureau. Enough is enough.
