I want to cancel this policy NOW!!!

We have been with Budget Ins with our car for a while now; then we decided to add our household items to this contract. The guy who helps us tell me telephonic-ally that he is going to insure all my household items for R50 000 so I don't need to price tagg each and every item. He also don't give un an inventory form. Our Canon Camera got ****** about two weeks ago. We went to the police station to report this, we put in a claim for our R8000 camera that was bought about almost 4 years ago. Beacuse we have no slips of proof of payment we must accept a little amount of R1000 or so. The inventory form was sent to us last week to price tagg our other items. I don't think moving to Budget was a wise choice. Defn cancelling here... we pay over R2000 each month for what? To be insulted price wise like this?
