Very Angry customer

Good Day<br> <br> I am so frustrated at MTN for their way of doing things. When my contract was due for an upgrade I requested for the account to be cancelled and migrated, the consultant whom i spoke to advised that I should not cancel as they are willing to provide me with lower amount on a monthly basis with the same benefits and with 100mb for R79, however as a customer I agreed to the option as I am trying to save on cost and could not afford the R249 on a monthly basis any longer, hence the reason I requested for contract to be cancelled. No papers of the new contract provided. I was advised by MTN consultant that because I am on a data package I could not cancel, Unbelievable I tell you when It was only one month. I am being billed for Data, cellphone, Package etc. then I spoke to a consultant named Megan who advised me that I am being billed more every month and MTN should credit me, WOW. when I called MTN, the response I get is, the customer was billed correctly. I will take this matter further than the complaint. I want MTN to cancel this contract and do not tell me about early termination fees, because this is not my wrong.<br> <br> I need feedback ASAP.
