Packet switched data calls

I have called 808 business centre plenty of times from my mobile and Telkom phone with no feedback, provisioning of my data and proof of the usage, reversal of data and charges or cancellation, I was at a MTN shop (President Krugersdorp) they also logged my query with a reference number ***, up to now nobody contact or let me know what is going on!!<br> End of August my contract ended and I think they switched the rates without notification, last six month average usage of R238,00 per month. September month R3104,34??!<br> <br> I would like the packet switch data reversed, the reversal of the data along with its charges as per contract and the contract terminated immediately with no further charges as the 24 months are up. I am from Nashua Mobile since 1999 with no hassles at all - but this is a disgrace
