Trying to leave review for great customer service

T-Mobile sucks ! I was with then forever and I left them because they tacked o insurance on my phone, and I told them I did not want it ! So I paid for it for 3 years s not knowning. And when I found out l, they only took off 1 month. When they started it insurance was only 10.00. Now it's 18.00never even telling me about the cost they changed it to. Very very poor customer service, they won't give me a proof of purchase now of ia phone i bought, that was stolen. I would never recommend them to anyone! SHAME on you TMobile u lost a good client
