Telkom - Home Affairs offline 2 days not able to do a Sim swap

On the 14 of July, I went to Telkom store in Kenilworth and while being assisted, I was told their fingerprint matchine is offline which meant home affairs is not offline and they could not give an ETA when it could be resolved and I had to walk around the mall for an hour and half and when I went back still they were offline. This morning I went to Telkom in Vangate mall, I got there the lady was less helpful than Cindy in Kenilworth center, she said they offline and does not know when it will be back online.She did not check or try and she if it works. I then also needed to block a Sim card and she called the call center which the agent advised they have system issues and hanged up. I then left the store u helped. I walked around the mall and on my way to the exist entrance I passed Telkom and the lady was standing at the door and asked her if they still offline and she said yes without again checking..So if Home Affairs goes offline for a month, does that mean I would not able to do my Sim swap? What other measurements in place for when this happens to verify the person?
