I don't know how much the representatives are trained but due to miscommunication with the lady who helped me to switch from my previous carrier to t-mobile I am stuck in a big problem.
Long story short, I switched 2 lines from a previous carrier with the help of representative who promised me that I will be reimbursed for the early termination fees and mobiles financing with the previous carrier (up to $650 per line), during the call she also offered me buy Samsung galaxy S9 and get one for free which I agreed to. After few days i found by accident that I can't take an advantage of 2 promotions at once (I am sure the call I made with that representative was recorded but nobody is interested to hear it). After 2 weeks of calling customer service they asked me to give up one of the promotions (while it was the representative mistake) but I agreed to pay extra $30 a month as I need to payoff my previous carrier. Now, even after I gave up the second promotion I call customer service each day twice and they put me on hold, give me promises, and promotional codes I need to place but nothing is working. The funny part that I sent them my trade-in mobiles (2 Samsung Galaxy S8 Plus) and I didn't benefit anything from that!!!! I am stuck now owing my previous carrier a lot of money, lost my 2 mobiles, and paying extra $30 for t-mobile each month!!!
Can anybody guide me how solve this problem? I am sick of calling many times each day with no serious solution for my problem.
