MFC - terrible in house insurance brokerage

I bought my vehicle and as normal you must have insurance before your vehicle can leave any dealership floor which is a common practice. I guess since I did not insure my vehicle with MFC I have been hounded with emails from their company insurance brokers requesting proof of insurance, if I don't provide proof of my own insurance they will take out their own insurance and add it to my monthly premiums as a threat. Please people think twice before financing your vehicle with MFC.
