MFC (3RD party sales) - BAD SERVICE

I have received a phone call from MFC selling additional product to my vehicle financing - dent cover. This was December 2019. To date I have not received any policy documents but I am paying for this since December 2019. I don't know who to contact. I have contacted the call centre trying to get the information but without any luck. Nothing. MFC takes my money but cannot provide a service. I can use R5000 every 3 months so the first R5000 is down the drain. I don't know who the 3rd party is who deals with the dent cover - no information received but I keep paying for the cover that I don't know how to claim from.
