Impossible to return faulty equipment to the store as instructed, employees who originally handed it to me said 'no'.

I got ripped off too and promised things to make up for it but no one I talk to seems to be able to help or follow through w anything. I am not very tech savvy so I relied on the lady helping me start up w t mobile and she told my the phone she reccomended was just as good as my I phone. OH MY GOSH ITS NOT EVEN CLOSE. its freezes, and glitches, doesnt pick up what I say when I use the talk to text, does not recognize my face or fingerprint. When I tried to take the phone back and explained that I was sold a phone on false pretenses they said too bad. I called in and someone aid they would make up for it by waiving the dep for an i phone no matter what the next person I was sent to said that person was wrong and that I was too new to get a smaller deposite so I am stuck w a crap phone that I have to use the hot spot for so I can just use my old I phone. So now I have to carry 2 phones in order to have 1 properly working phone. Oh and I am a nurse and it says they offer front line worker discounts but only for EMTs and firemen. I WISH I NEVER SWITCHED FROM CRICKET WIRELESS.I never had an issue w them and my bill never went up once in 12 years and so far in the 6 months ive been w T Mobile its gone up $40. T MOBILE DOES NOT HELP ITS CUSTOMERS AT ALL AND THEY DONT CARE IF THEY RIP YOU OFF AND THEY DONT CARE WHAT ANOTHER EMPLOYEE PROMISES YOU
