Shocking Bill and Bad Assitance

!EM The MTN response to my original complaint sounds very good BUT it does not address the fact that this contract was, from the very beginning, a 2gig contract. During the total period of the contract, leading up to the extremely high account, no bill was EVER invoiced for originally R119 and the R125 (after the price increase). The cap of R200.00 was made on the recommendation of the MTN branch assistant wen the seriously high bill was received. I did not art any stage change my contract and as such the account for the amount of R2800 was not only ridiculous but the unilateral change of the contract is not addressed. MTN seems focussed on my July visit to the branch but totally ignore the fact that THEY changed the contract from the original 2gig to whatever caused this outrageous bill. Please is there someone who can understand my problem and not keep on going back to the July visit. Proof of this extremely important concern for me can be found in the payment history since the contract was originally signed AND NEVER CHANGED even during the renewal of the contract. This contract was specifically for a student and the 2gig contract had a specific reason. PLEASE HEAR ME!!!
