Sim Swap issues

So I had to go to three vodacom stores first before I could do a swim swap. Mind you these are at different locations. Meaning a loss of money and time. Eventually at the Mall of Africa I was able to have it done. Now 5 days later my sim card is still not working. I called Vodacom customer care , and after waiting close to 10 min for an agent to answer my call , I am told the sim swap was successful so I will have to go back to the vodacom store where I had the sim swap done. Why should one go through all this trouble just for a swim swap???
