Car Mart reviews and complaints

I purchased a car from carmart on 3/24/10. I paid them 300 dollars down payment, and agreed to pay an additional 700 when my income tax return arrived (anticipated date of 3/26 or 4/2). On 3/26, I contacted Car mart to say our income tax return did not arrive yet, and we would pay the additional 700 on 4/2. I was told this was understandable, and to come in at my convenience to sign some paperwork. On 3/31/10, Carmart took our car from our home, and our private property contained within the car. I called car mart and told them they can keep the car, and I needed my carseat and stroller back which were in the van. Car mart salesperson Richard screamed at me over the phone, and told me car mart would sue me and take my paycheck. He also told me they would not allow me to have my car seat and stroller and CD's back. I have had to contact the police in order to get a police escort to retrieve my baby items and CD's. When I notified car mart, another male salesperson screamed and laughed at me, told me they would be suing me. Earlier, I attempted to explain to Richard the salesperson that I was in the hospital and did not have time yet to sign additional paperwork for the new due date on the income tax return money. He said he did not care. Additionally, the 700 was not required for us to purchase the car, as we required no down payment. It was an optional 700 we decided to pay.
