MTN upgrade Nightmare and still going on.....

I called 135 on 2 Nov to upgrade. Everything was correct and a few days later I received a sms with a different package. I called to enquire and was told that different packages was loaded than that which I ordered. They said I have to call ********** 241. I called and they said 3 days to wait to listen to recording. They will call me back. I called again after 3 days as I received no response. They advised that the upgrades was incorrectly processed. They will call me back. They never called me. I called today, the manager Leticia was supposed to call me but everytime I call she is not avail. Now they tell me I have to wait 21 days for the upgrade to be cancelled. Then the upgrade will be captured again and I have to wait another 7 - 14 working days. I requested the manager to call me again. Until now nothing. The lady that answers the phone is very rude. When I give them my id number they tell me im not on their system. Im so sick of this nonsense. A very capable guy named Theron is the only one that apologised. That actually speaks to me and explains what is going on. This is not my fault. MTN captured the upgrade incorrectly. The recording also shows that what I ordered was not captured. Why do I have to suffer now and wait another month before I can get my upgrade??? And they don't even have the audacity to call me back. Im going on holiday next month. When will I receive my upgrade?????? I don't want to hear im sorry. I want my upgrade now. If I went to the store I would have had any problems. Now im stuck with this. In the meanwhile I received 20gb data to use up in one month. Im also on another priceplan which is not even the correct one. When my phones are eventually delivered, where must I get data to update when you have already given it to me now on the incorrect plan???? I will NOT pay for this stupid plan and the costs. I even messaged the facebook page. They saw the message but did not reply. I mean what service is this??? Its ****ty!!!
