Vodacom Insurance Complaint

I would like to complain about Vodacom. All my devices that I have upgraded at Vodacom, they never informed me that I need to keep the sim card and the Cellphone together. I only saw this when I received my Policy for the Insurance that that is the case. Now they want me to pay R5 800 for a screen and I do not have that money. I really would not have taken out the sim if I knew that this was the case. The consultants must inform their customers that this is what they need to do.
