Bill exceeds more than double the account limit

Hi<br> <br> My internet bill is more than double the account limit. I have requested multiple times for an itemized bill which has not been supp**** yet. I began calling their customer care centre Monday 22 June 2015 multiple times in the day everyday making my request. I have also sent an e-mail 22 June with no response to date. I have written across their facebook page too with no interest from their side.<br> <br> They also cannot explain how the bill can be so much higher than the account limit which they set, and somehow the bill grew which customer care cannot explain as the account is blocked till payment is received at the end of the month, I would not increase the limit due to affordability.<br> <br> I need help to sort this matter out soonest please!
