BE CAREFUL OF OH MY CARS ITS A LOW DEPOSIT ****

They called me explaining to me that i was approved for a rent to buy car.I went to the dealership and they showed me the car.They showed me the contract that i was approved,so they said i my pay deposit so that tracker must be installed in the car.So i payed the required amount.After 4 days i called them asking about the deal. Then they said to me i need to pay more deposit .AND i asked them why they didn't explain to me before.So they **** to me saying i was approved.SO I ASKED FOR A REFUND AND THEY TOLD ME THAT ITS A NUN REFUNDABLE DEPOSIT.
