TMobile scam to give free device

The same happened to me I paid over a whole year another line because when I first got a line they told me I would receive a tablet if I open a wifi line I never received the tablet and about 6 months later I asked to have that line removed was told they couldn't do it I asked about 3 times with same response then finally on the 4th try someone helped me with it but already over a year I to want my money back never used that line at all but paid an arm and a leg for it
