S+>t survice

This month I get a account that's more than what I'm supposed to pay Cell C is not doing there work anymore, I'm very disgusted I had to pay July this year the full amount and email the proof to proof of payment and then July again but they still have not corrected the payments now when I'm supposed to upgrade in October it's going to reflect negative against my account, and this month again they have not taken the debt order what the f<"k is going on there?
