Account Query : 082 943 **** Ref [#***2]

I've subscribe to a MTN 500 package from MTN. One afternoon a sales lady call me from MTN and inform me that they have discount on their data package's, they giving existing clients the opportunity to upgrade from current package (500MB) data to 3GB data for only R89 per month. She reassure me that the total increase in cost will not be more than R100, I've asked her 3-4 times to make sure that there are no misunderstandings. On receiving my account they charged me a total amount of R485.56 for the 3GB data, which I have not received either. <br> I've phoned them numeral time and no one could assist me, I got transferred from one department to the next department. I then opt to email Customer Care (or must it be Customer No Care) on the 2/9/2015. Requesting an explanation/rectification on the account or the recording of the conversation whereby I agree to the 3GB data at a cost more than R100. All response I've got from they, they will look into the matter and contact me. I have email them again with no response or solution to the matter. They've issue me with a reference number #***2 that's as far as it went.<br> I request that they contact me that we can correct my account
