Poor MTN Service

Something is seriously wrong with MTN. Over the past three weeks I have received three sms's advising me to visit the MTN store at Bedford Gardens to upgrade. Upgrade date was noted as 01 February. As I stay in Meyersdal, I visited the MTN store at Mall of the South). The person (no name tag) contacted the call center as the system showed that my sim card is not activated. Strange as I can make calls, receive messages etc. The call center advised her that I can only upgrade on the 3rd of February, but that I need to visit the other MTN store at Mall of the South, as she can't access their new system. So I walked to thee other store. The lady there (also no name tag), took down my contact details (as they did not have a toner for their printer) and would have phoned me. No call received as yet. So I had a look at my MTN app this morning. The upgrade date there now shows 05/03/2020, which is different from the date I had earlier this week. This morning I phone the call center to ask them. Spoke to Gloria. Gloria now advises me that the upgrade date is only on the 3rd of April. What is going on guys?? I have now received 4 different upgrade dates? If I look at your rating of 2.1 out of 5 on HelloPeter, coupled with my experience the future looks bleak. In case someone cares, and would like to assist me, my number is ***. Waiting in anticipation, but not holding my breath.
