MTN customer service

On Friday night, 24 September a cell phone which is on my MTN contract was ******. I reported it to your call centre on Saturday morning, 25 September. They suspended the Sim card and blocked the phone for me. I was advised to go into a MTN store on Sunday, 26 September to request a Sim swap for the same number. I visited MTN store in La Lucia Mall, Durban on Sunday morning, paid the R150 and completed the necessary documentation. The agent assisting me advised me that the new card will be activated within 2 to 24 hours. By Tuesday, 28 September the new Sim card was still not activated. I then had to make numerous calls the call centre (of which I have numerous reference numbers) but this issue was still not resolved. The call centre informed me that everything on their side is in order and that the MNT store is responsible for the delay as they cannot see any Sim swap logged on my contract. I then had to drive out to La Lucia to go to the store as they were not answering their telephones. The manager at the MTN La Lucia store then told me that the call centre does not know what they are talking about. He then phoned the call centre and told me that the issue is a system problem and that my card is the only one that this has ever happened to. You can imagine that emotions were running high at this stage, and instead of him trying to calm a customer and helpfully assist he started shouting at me as to not tell him how to to his job and that I can wait in the store if I want (because I told him I would like it resolved before I leave) but he is locking up at 6pm so I should do what I want. He did apologize for his attitude towards me, but unfortunately this was not acceptable. He advised me that the issue is now with the Customer Service Consultant of whom I cannot directly talk to and that he will keep me updated as to the status. When I phoned the call centre from the store they advised me that since the issue is now with the Customer Service Consultant there is nothing further they can do to assist me. Today, 29 September this issue is still not resolved. I have the new card but I cannot use it. The store manager did phone me at 10am today to advise me that the issue is still not resolved and that he will update me by 12 today. He phoned again at about 2pm to tell me that it is still not resolved and will update me again at 5pm. It is now 4 days since I paid for re-activation and still nothing. This is totally unacceptable from MTN. Apart from the absolutely terrible service from the La Lucia store I am also highly annoyed with the whole experience between the store and the call centre. I keep on getting emails from no-reply MTN regarding the various reference numbers advising me that the issue is now resolved, but this is not the case. I still have a Sim card that is not activated. I can understand the 24 hour wait time but 4 days (up to today) is not acceptable.
