I bought a car recently and was scammed by a woman by the name Rose Luz , from Houston,Texas which is the seller ,who is still selling this car today when I purchased a lot of money and I am trying to get a hold of eBay but have no luck this woman needs to be cought before she continues to take more money away from family in need of a vehicle or so. There has to be some kind of justice on this. I tried contact eBay several times by email only to get ignored. I also tried to contact the seller but also to be ignored as well.
