I bought 2 cars in a time span 5 months from Court...

I bought 2 cars in a time span 5 months from Courtesy dealership and its been the worst experience of my life. Basically I bought 1 bad car had to trade it in for another. The first dealership Courtesy Volvo sd if I stay within Courtesy dealership they would help to make things right The warranty coverage from my first veichle that I purchased I was told I would get a refund when I traded the car in. I was told by both dealerships I wouldn't need a down payment for the second car because they were working with me because of the first car problems and how I was sold a bad car! Instead they took my refund over $2000.00. Next the first few days after buying the second car. I had repair issues and also a bad tires. So since they took my warranty refund.I was unable to purchase or apply my refund to this car!Long in short I was given a hard time,had the car one week they had it almost 3 weeks. Got the car back again told them still had issues.I had to call the owner of the dealerships and explained what I been going thru and how the dealership had my car more then I did and I explained what I been going thru has been a horrible experience and I was abused in my car contract. Nobody contacted in regards to none of my complaints. I expressed it wrong to take advantage of people! Why waiting for my car to be returned to me, I met lady who was going thru the same issue as myself. All I can say I will never buy any cars from any Courtesy dealership in Az again. I tried to make complaints to get help because I felt I was taken advantage of. Unfortunately one if the workers said I bought a used car and they all have issue and that what I should expect! I would like to say it unfortunate Im going to take what ever avenue to be heard. What's so bad I had my a friend as a witness to everything that happened and they just dont care. Well I care because they have there money for the purchase of both cars and I have left with being disrespected as a woman in general when I told them about repair issues and I was questioned how I knew I had issues. Every time in my defense, I said just because I'm a woman doesnt mean I dont have a clue about cars and what wrong with them. I Know I'm not the first or the last person to be taking advantage of. Beware and do research!!!!
