MFC charges interest on value added insurances

I was called by MFC offering me a very good deal on Scratch and dent cover. R75 a month. So I signed up. My vehicle is financed by MFC and it was stated that this offering is only available for existing MFC customers. What they do without stating as much is finance the full amount over the term of the policy and add it to your Vehicle finance amount. In essence they gice you a loan that pays the policy upfront and then they are able to add interest. I was qouted for a term of 24 months. So the R1800 that it should cost now costs over R5000. They dont tell you they are financing the amount upfront. Who wants to pay interest on insurance. Is it even legal.I assumed a deduction of R75 as stated monthly. I think Nedbank does this with all their value added products as they tried doing the same with my home insurance. So they are sucking every cent they can from unassuming loyal customers. This kind of business practice is completely ********* in my opinion. As much as I think the product is good I think you are operating as loan sharks using your financial muscle to suck the life out of your customers. I cancelled the policy. I wont be paying interest on insurance.
