EXORBATANT BILLING // FAILURE TO RECTIFY

I have a data contract with MTN. Throughout the existence of the contract I've had an average spend of R 400, come month 24, the final month of the contract and only upon enquiring about an upgrade, I was informed of an account well in excess of R 2500. I disputed this amount on various occasions and to date I have not even received an invoice for this amount. <br> <br> Despite having complained MTN fails to provide me with the information as requested.<br> <br> I refer to another report I have made on the 17th of June 2015, to which MTN only responded \the information was sent"(REQ:***)<br> <br> MTN has now proceeded to blacklist me"
