Warranties 2000

I bought a car from a small dealer near Leeds and i asked them to provide a very good warranty on the car so the dealer got me a Premium plus warranty through warranties 2000 which i was charged £400 for and was supposed to be the best warranty available that covered virtually anything on the car. However after weeks of owning the car no paperwork was issued to me to confirm i had warranty. I called warranites 2000 several times and stared to get very annoyed that they kept telling me i was covered but didn't have any paperwork. I demanded a refund because it was very obvious that this was a DODGY company that just take peoples money but they refused to give me any money back. I even checked the legality of obtaining a refund and apparently I had 2 weeks to cancel and get a refund within 2 weeks of receiving documentation. i told them this and they refused and just printed document on an ink jet printer on A4 paper to shut me up. The piece of paper said my warranty was for a maximum of £1000 per claim and a total limit of £2400 for the year, which seem fair enough but no break down of how they cover items on the car My car then developed a fault which is going to cost £1000 to fix, Warranites 2000 have told my mechanic that they will only pay a contribution to the cost but haven't given a figure. they wanted to know the mileage on the car which they have been given now so we are waiting to see what they offer. We are expecting it to be a worthless amount so i plead with anyone buying a car warranty
