So Disappointed with Vodacom yet again

I signed up for a business data contract and received the 5G router on 10 December. On 11 December I contacted the agent to inform them I had received only the router and NO SIM card. Been patiently waiting and following up weekly but still no answer as to when I will receive a SIM card. It's almost a month since I signed up and I still have no WiFi. The response I receive is always that it has been forwarded to back office. That's since day 1 and I've not had any update from "back office"
