Telkom mobile after sales service with number change

I switched to Telkom mobile in October 2021 . They eagerly signed a new contract with me and delivered the phone within 2 weeks. I then requested a port from my old network in order to keep my old number. I asked the lady at the telkom kiosk, if we shouldn't use the sim send with the phone. She rep**** that she will use a new sim. The port took a few days, but then my old number was allocated to a prepaid simcard the lady gave me and not my contract simcard which came with the phone!

I was told to do a number change, to connect my old number, to the contract. I have requested tuis on 28 October and was told the turnaround time is 72 hours. As today, the number change hasn't been done. Calling the telkom mobile line brings outcome, as they continually says I will receive a call back l, or that they are busy investigating. Seriously, it has been 12 days and it hasn't been resolved. I am very disappointed with this service!
