MTN *****

On the 11th of May I received a call from the MTN consultant and we were discussing the upgrade of the Device on the 078. The price that I saw online was R399. After 5 to 10 Min he called me back and said that the device was R429, I then told him to leave it as that is not the amount I saw. I then went to the store and at the store they informed me that the 071number has been upgraded to 8gb of which I didn't agree with. I asked for the upgrade to be reversed because it was done without my consent. I logged a complaint via email and the feedback was that the complain was invalid. But yet I don't have a device I was upgraded to on hand .
