Auto Premium Car Sales, Newlands, Randburg review: I bought a car from auto premium car sales

Good Morning, I bought a car from Auto Premium Car Sales this year on the 18th of January. The value of the Care was R70000 and I paid cash for it, I've also got a R5000 discount. I asked them if the car is in 100% condition and they told me everything is working on the car which was a lie. Two days after I bought the car I've noticed that I had no hooter on the car and both airbags was missing which tells me the car was on a accident and I wasn't told about it, so I went back to them and requested my money back because they lied to me to get the sale, if they had told me all this details I would've bought the car and they refused to pay my money back, they than offered to fix the car and asked me to pay them the R5000 discount back I'm order for them to fix the car which I did in March and they only replaced the front shocks with second hand shocks and two old tires in front that's cracking now and needs replacement as well. I'm still waiting for them to replace the airbag and the ignoring my calls and messages, is there a possibility to get my money back because I can't drive this unsafe car with my family. And I've also paid them R3000 for change of ownership and I still haven't received the car papers from them yet so I don't know if this car is roadworthy... to be honest this car won't pass a road worthy test.
