I recently set up a payment arrangement (only two choices- full or 2 payments.. not much of a choice there...) but I was able to pay the first half on my own already so now I wanted to cancel the payment arrangement but seems I can't and am not too happy because I don't have enough for TMobile to take the 1st payment that was 'scheduled' from my bank account. (the amount left would be or should be the 2nd payment).
would like an option to at least edit or update to say that I was able to manually pay the 1st payment early!!
