Data Usage

I was just on the phone trying to sort out my account that I was billed for R1020.38 data usage in May 2015. On the first call I was cut off before even speaking to a consultant, on the second phone call the agent just refused to help me and ended the call.<br> <br> I have never used that much data, the last 6 months my data usage amounts were: Nov 14 R0.00, Dec 14 R50.70, Jan R0.00, Feb R0.00, March R91.47, April R5.81. So how can it be remotely possible for May to be R1020.38???<br> <br> I have cancelled my all my contracts with Vodacom and this is the last one and I cancelled it for end of June, now you want to make extra money from me because I cancelled all my contracts.<br> <br> I will not pay this amount at the end of the month, I will make a transfer only for normal subscription of R627.90<br> <br> It has not been a pleasure at all doing business with you!!!<br>
