Bank of the West insurance scam San Ramon, California

During the last year the bank harassed me about car insurance. They said I didn't have any. This was between April 2012 to September 2012, they said my payments would go up to pay for this. I called my insurance company and informed them about this and they said it was taken care of because I have always had insurance on my vehicle. This April 15, 2013 they repocessed my truck for not having insurance on it plus late fees that are a result of that. I have been with the same insurance company the last 15 years. When I called the bank they said they charged me for it now I have to pay. I have been paying on truck now for 4 years and owe what a general manager at a car lot said was an extraordinary amount of money on this vehicle when I was looking at new cars. At the rate it was going I would never have been able to pay it off. After paying on the truck for 4 years I still owe 22,000. My Insurance companies phone number and insurance documents on request. This bank should stick to banking business and quit trying to steal from people.
