Worst service ever from Vodacom

I upgraded with Vodacom in March, got my 2 iPhone 15 and the SIM card for my second phone that I’m supposed to get airtime on every month didn’t work even after I called Vodacom and was told the sim card is activated. Vodacom was going to send me a new sim card and after contacting the courier company,I was told that the simcard was returned to Vodacom as they couldn’t get a hold of me and the reason for that is because Vodacom gave them my child’s number instead of my number. I called Vodacom and the agents couldn’t assist me. I’m paying every month religiously however I still don’t have a SIM card and my airtime and we going into the third month now. Vodacom just keeps disappointing me and I have to fight every time to get assistance. This is not on!
