Bad customer service.

I have tried from the 10 January 2019 to do a Sim swap with the jet/Edgar's airtime helpline. As I lost my Sim and wanted my old number back. Was told to get an unricad Sim card, which is hard to get as no shops will sell me one. I missed the call on the 11 January 2019. When I called back they had closed the query. I again called on the 14 January, and got a call from Owen Sibeko at 16.23 on the 15 January. He couldn't help as the Sim was a rica Sim. Finally on the 18 January I got hold of a Sim card from the cell c ppl at the local taxi rank. I called the call centre as Owen instructed me me to do so and tell them it's urgent for him to contact me. Waited the entire day and no call. So frustrated that they say 1 thing and do the totally opposite. Plus Owen and his department do not work on weekends so how does that help a person
