Drivetime ripoff,scam,crooks Internet

I bought a 2008 dodge advenger from drivetime in irving texas on nov 15th 2012.The next day the engine light comes on so i call the warrenty people and they send me to a repair shop i spend all day ther and im told it was just a bad coil and it was replace i also had reported a problem with the sterring and was told i had a busted tire rod which was repaired.So the next day the engine light comes back on i take it back to the same shop and im told since its a sunday that they could not look at it because drivetime warrenty was not open on sunday.So i call drivetime again on monday and im told to take it to a different shop well on the way to the shop the transmission starts slipping very bad so when i get to the shop I wait for 8 hours until thay will even look at it then im told the transmisson will have to be rebult I call the warrenty people about a rental and when i get to the rental place im told im responsible for the deposit and all chages over 25 dollars a day that drivetime wil pay.So almost two weeks later im told the transmission is rebuilt but the engine is bad and needs to be rebulit or replaced three days later still no word from Drivetime then i get a call from the dealership and im told i need to come in that they would not replace the engine but they will put me in a car of the same value and style.well when i talk to the salesman they are trying to put me into cars that are years older and have thousands and thousands of mile more than my car.Also they take my car from the repair shop and have it taken to one of ther dearlerships without my permisson.When i tell them the cars are crap they are trying to give me and i ask for a car that is close to mine but costs 1200 dollars more they tell me i would have to pay 2500 dollars more down payment.These people will not call you back are give you a straight answer on anything.Now they have taken my car which ran when i took it in but now it does not.So i have no car and they have taken my money.Does this sound like good business to anyone?Again beware of these people.
