No care for customers

In December I took a contract and the device was not delivered so I cancelled the contract. The first payment of approximately R1000 went off my account in January and I was told that the adjustment would reflect in the subsequent month. I then received another bill for the contract that was canceled and the adjustment for the deduction in December was not actions. I have been dealing with Neo Makoti and Yashoda Salikram. After several complaints, Yashoda referred the matter to the area manager - Farida.After 5 days I did not received even a courtesy call from the Area manager Farida.She has sensitized about the urgency of the matter and I have been waiting at the store for her call but she continuously says that she is in a meeting. I am absolutely disappointed and disgusted at the poor customer services. I have been a loyal customer of MTN for more than 15 years and this is what is damaging the reputation of your company.I appeal for your urgent intervention.
