Report T-Mobile to the FTC

This is LordRoquefort with an explanation on my post. I called T-Mobile for advice on my pre-paid account because I would be working out of the country for two months and didn't want any hassle or phony roaming charges. I paid eighty dollars ($80) in advance to cover two months. I did not text, call, respond to anyone unless it was over free Wi-Fi/WhatsApp.

They still sent me threatening messages that they were going to suspend my service the very first month.  I'm in South America and added 40 dollars to my account. Month number two. The same scenario and added another 40 dollars. I have proof of the bank transactions (withdrawals). I paid 80 dollars in advance. Where's the 80 extra? When I called about the issue they made up charges on the fly. Supervisor transfer. Travellers fee. Bringing my cell phone to another country fee. Looking at my cell phone outside of the USA fee. And! My bill was 35 dollars a month initially. Then 45 then 35 then 40 dollars a month at their choosing.
