Drive time Sold me a bad vehicle lemon Plano Texas

 I purchased a vehicle from Drive Time in Plano Texas and I only had it for a few months before I started having engine brake problems.. I've contacted Drive Time customer service without getting no help from them and I have paid my bill on time never missing a payment for two years now.. The vehicle that I purchased was a 2008 Saturn SUV.. The vehicle has broken down four times and my mechanic tells me that the motor and transmission is about to go and there's no parts for saturn anymore. Call Drive Time customer service again I spoke with a representative which was very rude to me I explain to her that I couldn't pay for vehicle that Wasn't working.. I asked her could they give me a another vehicle and we'll go from there she stated they don't do that so advise her that I will be bringing the vehicle back..
