Vodacom does not care for their customers

I recently upgraded with Vodacom and the consultant promised me an additional SIM card on my line and upon inquiring afterwards on the delivery no one in Vodacom are aware of the SIM to be delivered. When I asked to speak to her to confirm I am told that I should continue calling until I get hold of her at some point, so I must try and resolve their issue. I am a RED VIP customer for numerous years and that is how they treat me. Absolutely pathetic.
