...TMOBILE FLEX PAY ACCOUNT ? How can I cancel my Tmobile Flex account? I have it for 1 month now, I want to get pay as you go, I called customer service and went to the store 4 days ago, they said it will be cancel but still not cancel yet! They already charged my credit card for the next month since they told me I have to set up the credit card billing auto billing, it was a mistake to do this, now they wont cancel my Flex account. How can I cancel ??
