Data Billing - ***

Hi , <br> I received my monthy bill for June in the first week of July! This Bill was for the amount of R4174 of which R1900 was data charges. <br> <br> I have NEVER used this much data with Cell C and the breakdown shows very expensive data calls at extremely odd times! I contacted Cell C on the 14/7 and requested Data validation,I contacted again on 17/7 , the lady re logged it . I was promised feedback in 48 hrs. On the 28/7 I followed up again to be told it will take a month . I contacted early August and was told they would mark it \Urge".Today 12/8 I receive an SMS to say that they have validated and it is valid! Seriously? 1 month for that ?<br> <br> I cancelled my debit order for the end of July and have now paid R2200 which was the calls and contract part of the bill. I have not and will not pay the R1900 until I have a full explanation of 2 things: 1) what is this data for?How did it happen when I was not actively using my phone at these times? As a so called Red Carpet client I was not notified that I was operating out of bundle to this extent ?? I have always topped up historically with a bundle if required.<br> <br> I req proof of what this is for and will not pay more than bundle rates."""
