Still no car

This is my second review in two weeks. I bought a car two weeks back. Complained last week about car 52673 took car back last week Tuesday to we buy cars Midstream and now I'm being ignored,after numerous callsd .Manager Damien advised us to bring back car they will fix it now our calls and messages as well as emails are being ignored after we paid almost 500k cash...I guess they keeping car and our money. Manager I'm referring to is Damien and also Hannes Manager of call centre so what now. So it's only a money thing I wouldn't be surprised waking up 4weeks later while my money is in their account generating for them and probably being sold while I'm waiting for them to attend to me ...
