Cell C *****ing my money

I got my April statement from CellC, on which I disputed some charges. They charged me for data used outside the bundle, even though there was still data in the bundle if you look at the itemised billing. I am on a Giga20 contract, and they are taking data off my PEAK bundle while it is after 12pm and should come off the MIDNIGHT data. I am feeling cheated **********.<br> I logged a request with the call centre, which they 'resolved' by sending me an itemised bill and the ip addresses of sites I visited. This did not resolve my issue, and I contacted them again numerous times after this.<br> They have not given me any feedback and just happily taken my money. I would like to know why I was charged for data used inside my data bundle.<br>
