Incorrect Data Billing

A data spread sheet from Cell C via our service provider clearly shows that over 80% of their data lines are invalid because the uplink value shows 0 but the downlink value shows 500MB. If there is no uplink value there cannot be a downlink value. The consequence is that every customer billed by Cell C over the same period - will have received incorrect bills. We have not been able to get a response from Autopage on the issue despite sending in clear evidence of the mistake - but we are still getting a bill of over R13,000. I think every client of Cell C for the period of the first two weeks of June this year - should insist on a data report for that period. We were billed for 15GB of data - on a 3g modem for a period of 5.45 hours between midnight and 6:00am in the morning - another impossibility! Autopage have not even rep**** to our documents and just keep sending the same bill.
