they dont pay customers for their cars.

I was called by Hibrid auto in Ridgeway.They called me to buy my car.I took the car and spoke to the owner Rajin Pillay.he told me he will pay me R107 500 for my car.R20 000 as a deposit and the 87500 exactly after 7 days.that agreement was in August 2017,til today i have received no other payment.Ragin pillay blocked my cell number upon calling him.His manager Dillan keeps telling me he wll pay me the next day.but they dont.until i have no money.they dont want to release my car back to me.
