SIM SWAP MESSED UP

I purchased a new cell phone on 23rd June and I needed a smaller sim card for it. I went to MTN Ferndale on Republic for the swap. Somehow the swap was messed up and I had to go to the police station to get an affidavit to state why I needed the SIM swap. I did this and took it all back to the shop. The consultant said the supervisor would have to override the swap. Turns out the supervisor is sick or not at work, so this swap has come to a halt. This is all well and good except I need this SIM active, so I can pay salaries. So where do we go from here?? Please advise This is not good customer service.
