Insurance cancellation nightmare

This is the worst insurance ever, when you join their insurance they claim it's a monthly premium insurance but when you want to cancel,they make you jump hoops and still deduct your monthly premium after cancellation. Claiming you need to give them a month's notice...though you pay a premium to get covered, I told them my vehicle is sold hence my cancellation, now they want me to proof that I sold it. I have been with many insurance houses,this is the craziest thing I have ever heard. If you want head-ache Insure with pineapple, it's a mission to get out. Not even going to continue with my other vehicle
