MTN-Mondo

A lady called us from Mondo informing us that our current package with MTN will be upgraded at no extra charge. We asked her about 2 times if no changes to our monthly bill will be made and she assured us telling us she was merely informing us of extras included in our package. Come month end, our bill was increased by more than R100. We called MTN to tell us why our bill was now higher amd were told that the phone call we had gotten from this lady from Mondo was a package change and we should communicate directly to Mondo. It's been over a month been told our case is being investigated and the last communication was that Mondo listened to the recorded call and l the customer agreed to this change which l surely know l did not. I asked Mondo to send me the recording so l can listen to it myself amd lm being given the run around. I am being told we need to go to the MTN branch in Fourways and Mondo will send the audio there. Why do l need to go to an MTN branch when MTN was supposedly not the ones who called me. Mondo works from Mon to Fri and l work as well. When do l have the time to drive to Fourways for an audio that can be sent directly to me. Why does Mondo even have my sensitive information such as ID number when l opened my account with MTN isn't this sharing personal customer information to a third party. This is ***** and l don't take such lightly. Why are Mondo employees calling customers and **********ly changing packages when there's no agreement. MTN is committing business suicide by involving such third party companies l tell you
