Dkr Auto Sales Llc, Cincinnati OH

I purchased a vehicle from the car lot on January 31. I purchased the car under the understanding it was a 2010 and found out it was a 2008 when I went to get insurance on it. The car has broke down 4 times and motor as blown with being told there was nothing wrong with it. I have tried to get the title to vehicle and the dealership told me they had no record of me purchasing the car and they told me they have mailed my title to me but after going to bmv I found out the title was not transferred to my name till March 4. I paid cash to this car so why did it take so long to transfer my title and why did the dealership hang up on me and get down right rude over this.
