Mega Motors RIP off Dallas Tx

 I payed a down payment of 400$ on a red 96' montecarlo and found out 3 wks later the motor was going out called mega Motors and described what was going on with the car they tell me not to drive the car they will send a tow truck to pick it up which it took two days before they decided to pick it up it took three days after that for them to tell me the motor was going out and tell me to come pick up another car and bring 200$ because I was late on my payment which I wasn't they picked the car up before my payment was due.

But I brought the 200$ and told them the car I wanted but they told me I had to pay 400$ more on the car which I only had 200$ and then they tried to pick out a car for me when all the cars they showed was beat up look like they been in multiple wrecks and front end of the cars were completely gone and also the switch to use for the signal lights was broke and hanging off and they showed me four cars like this and I wouldn't take it and they refuse to give my money back I'm about to lose my job due to this and they are very rude and inconsiderate!!!!
