Issues with porting a number for MTN contract

On 15 Dec, I visited the MTN store at the Phoenix Plaza to upgrade my phone and to get a contract for my brother. He has a prepaid Telkom number that he wished to port to MTN. Up until my post now, I have still not been able to get the number ported. The local MTN salesman initially said that it was the festive season and the porting division was on leave, and says that the issue is still unresolved. MTN should take off the advert on their website that misleads customers into thinking that porting a number is simple when it seems complicated. I called the MTN customer service and was given three sets of differing information. The last was that the MTN office is supposed to escalate the matter and I can't do anything from my side. My brother went to the MTN Cornubia store for advice, and they said that such issues are usually resolved within 48h and it needs following up by the salesperson. I already started the process and don't want to start from scratch. I would really appreciate a response from MTN because your service agents, in general, seem quite unhelpful. I'm so irritated at this point, I'm not only thinking of taking out the contract with another network, but also taking my contract there as well. Ive had an MTN contract for the last 17 years.
