Finance *******

I am told there is a clause which states I am going to be randomly requested to provide proof of insurance. I ask for my signed copy where that clause is indicated and instead I receive an email telling me I have been added to some useless insurance and my payment is effective this month . Why the hell should I pay double insurance because I already have a comprehensive cover? Also why the hell would I even insure with freaking VW who connected me into some ****ty contract to begin with? I am in my last payment year and have had comprehensive cover on all my vehicles since day 1. They need to cancel their insurance because I don’t need it, I have my own cover!
