MTN PAVILION UPGRADE

In May I went to Mtn pavilion branch for upgrade, I needed a new device Sony experia and I had a top up package my 200. The consultant explain to me that it's called my choice 200 and I said I would to continue with my with the same package. The following month mtn sent me message that I should pay more and I was confused because I only knew that I need to pay a fixed amount. After the strike I managed to get some clarity from the call centre that my contract it's open line and advised to go back to the shop where I did my upgrade I had to drive about 230 km back to Durban of which the consultant Viwe assisted us but to date the problem hasn't been resolved, after two trips that I have made to the shop. The consultant told me that there is no thing he can't do now and promised me that the manager Fazila will contact me about a week ago but I am still waiting for their call even the consultant is not returning my message either taking my calls. My outgoing services has been cancelled because of the amount that they want me to pay because of the open line.Krish did acknowledge the error on mtn side and promised that it will be resolved of which it hasn't happen yet
