Worst customer service

I have been lied to 6-8 times by T Mobile after they almost doubled my monthly bill , and no follow up after promising action . Going on for over 3-4 months and every time i called someone talked then their supervisor and same conversations and then "we will take action and update" . Then no update and finally on Sep 1 2024  a rep said they were able to offer me a discount for my patience as loyalty discount and will take effect in a few days . Again nothing and after my auto payment again was for the big amount I called back again on Sep 9 2024 and they needed 48 hours to review and update . It's been 11 days and when I called today same motions and when o finally told a supervisor that I have had enough of the same explanations and conversations that they should focus on living to the promise of the dowocujt that was made , they said sorry you can't talk and so you can leave T Mobile if you want and stopped the call . 
 

I will make sure I post this with all details on all possible social media tagging all my fgrieds and take this to as many people to stay away from T Mobile as I start looking to either go back to Verizon ( whom o only left on December 23 as I was proofed $40 per month lesser and now am paying twice that to T Mobile ) . It's a lie and cheating and will also lol at legal options to be paid for all the time I wasted all the agony and frustrations and of course the overpayment 

am also surprised at the incompetence and how every new person had no clue on what happened and what conversations I had earlier and kept asking the same questions and tried having the same conversations with me all the time . It's 2024 but their process feelS like 1980 . Will write to their COO too on that
