T-Mobile USA review: Very bad customer service.

I have been a customer with t-mobile and i've always liked and respected them for having exceptional customer service. On November 28th all of this changed when I attempted to take advantage of a promotion offering me a free iphone 14. I figured it would be a great gift for my daughter. I completed my order so i thought with a tmobile customer service rep. that promised me my phone would be to me the next day as he put it in for overnight shipping. In addition i added in an apple watch. both were promised to me for the next day. I waited 2 days only to receive nothing. I called their customer service line again and was told my order was never processed. I said ok as i have alot of patience and i understand mistakes happen. The rep reprocessed my order and he also promised my merchandise would be to me the very next day. I was happy about the call and went about my day. 4 days go by and still nothing so i called 611 once more only to be told the same thing the customer service rep prior to the first one told me ; "mam we are so sorry your order was never processed. At this point im a little irritated because this is my 3rd time calling about the same issue and nobody knows anything! I then gave the rep my order numbers and she was able to see my order. The rep then stated that the reason I did not receive my order is because it was on back order but not to worry because it would be shipped to me before the 13th of december. Well that date came and went and I never received anything. So I called back for the 4th time only to be told my order was never processed ! Then after me giving the rep my order number he explained that i needed to reorder because it has been almost a month!? By now I am absolutely infuriated! The rep really had the nerve to tell me to trust him?! Yeah right. I did not want to speak to him any more so I asked to speak to a manager but he refused to let me speak to one stating he helped me already. Like who is he to tell me a customer of almost 5 years or any customer that they can not speak to a manager?! I called back and tried to get the issue resolved again and was denied being able to speak to a manager. Called back and asked the rep to send me to a manager. He agreed but I was contacted so late by the time anyone called back it was 10 pm I was sleep by then. The moral to the story is I thought more of Tmoble and and now i will be canceling with them and insisting that everyone in my family as well as all of my friends cancel as well. How dare you treat customers like trash and tell lie after lie then refuse them any resolution. It is christmas time and its the wrong time to be telling someone they will receive something then put them through trauma for being a loyal customer. I hope you fire the people that did this and i plan to use my voice as well as my computer to tell my story. I am a social media influencer and i will warn all of my 1million followers to never get your service. I am completely scorned about all of this. You guys should be ashamed of yourself.
