Terrible customer service and processes

I have never seen such an *********** team. I called 2 days ago to change my physical sim to esim. I was informed that my number was flagged and I was told to contact my company. I requested the so called supervisor to send me an email she promised to by never did. Today, I tried and call the customer service and my number doesn't go through, I have been blocked because my number has called them too many times by that they mean twice. I was not informed of this and I still cannot get assistance not from the vodacom store I went to and not Tobi since I cant get through to customer services. No one can assist at this point🤬
