Tmobile is doing false advertisement

When I log in to my T-Mobile account it says I qualify for the upgrade of the IPhone 14 pro at $0 down and $41 monthly. I decided to go for it, I select the phone I want to upgrade (not trade in) and it ask me if I would like to pay full balance or proceed with zero down and $41 monthly, and once I select the zero down option and make it to the end, it proceeds to say I need to make a deposit of $249. I called and a rep told me that a lot of costumers were getting that message and it was a glitch in their end. I asked If this can be honored  because I've never had to put a down payment and have been a costumer for 10 years, I was told they were going to look into it and give me a call back in 48hrs to see if deposit can be waived.. SURPRISE!!!! I never got a call back! So I reach back out and was told my account was reviewed by their "overseas team" and no notes were added and that the supervisors are all in a meeting and can't talk… how convenient 🫠 I swear this company just gets worse every year
