The fools at T-Mobile need to wither away... and I'm no fan of AT&T either, but T-Mobile has gotten simply impossible to deal with because of their financial lo$$es. For example,
I have (had) an unlocked iPhone on T-Mobile because I'm retired and do not need data. Just voice and no text, no data. T-Mobile made a change in August/September and took down the T-Zones sandbox/firewall... and our two iPhones decided it would be fun to play on the network instead of WiFi... completely unknown to me... until I got my first bill statement, after it had been processed by MasterCard... Just an FYI, never, never, never let a mobile operator automatically debit your cards. I contacted CS and got the run around and after escalation after escalation, I finally got the data stopped, but the manager was not able to give me credit for the data bytes already billed. I contacted my MasterCard host and send them pages and pages of online CS conversations, one where they admitted to making the change without customer approval. MC issued a temporary credit while they explore the issues... they are my "proxy" in this matter.
Well, Friday I get a notice from T-Mobile threatening me with a bad reference to the credit bureau AND being turned over to a collection agency. Not only did they bill me for the amount in dispute, they added $25 as a service fee and gave me 10 days to pay.
SO MUCH FOR T-MOBILE CUSTOMER SERVICE... THEY DESERVE TO FAIL.
