the ability to listen and compute the correct info

I cancelled my insurance with Budget CLEARLY stating that my car had been SOLD. They sent me a confirmation letter clearly stating that my car had been ******. This is not acceptable at all under any circumstances as when i went to another insurance company they asked whether I had a vehicle ****** within the last 7 years, i said no but if they phoned checked with Budget (previous insurer) they would have seen that Budget stated ******. If you give any incorrect information to your insurance company it makes your policy null and void. I am NOT impressed.
