MTN Service Levels are shocking

MTN contact centres are completely useless. They contacted me to inform me I can action an upgrade. We then agreed on a suitable package to be implemented. by the 15th nothing has been actioned and I had to phone in again to follow up. I spoke to a consultant and was told that they can see I requested the upgrade but that it has been cancelled for some unexplained reason. We then agreed on a new package again and I gave the go ahead to do the upgrade. By the 18th I have not received any feedback regarding the upgrade, and I was forced to phone in yet again since I was informed that an upgrade will only take 24 hours to implement. Upon speaking to yet another consultant I was informed that not only has nothing been done regarding the upgrade but in addition the package I was sold does not include the benefits that the consultant explained to me. I am extremely frustrated in that I constantly have to phone in and check up on why nothing is happening, and the upgrade does not get actioned. In addition, the fact that the consultant miss represented the package agreed upon is unacceptable!!!
