Extremely bad service

We bought a countryman mini from SMG Durban and received it on 31 July 2015 (after it supposedly went through an 80 point check). On 3 Augurt 2015 the car had to be towed to a dealer as the engine overheated. No warning of water levels being low or depleted was given by the mini. I stopped at the nearest garage (as I was on my way to Jhb where my husband was on training. It was only me and my 2 year old son). The attendent at the garage informed me that the car was totally empty. After a report was issued by die dealer that inspected the car, it was established that the car's thermostat and -housing were broken, the waterbottle was broken therefore the low water level and car had no antifreeze. We've been trying to get this car back to our hometown since then. We've paid insurance and the installment is due soon - FOR HAVING A CAR FOR FIVE days??? Imraan is now passing the buck from who needs to pay / or they are going to pay the towing company by eft, today he said no they are going to pay by cheque?? Then in one sentence he ecpect us to pay the towing then they will reimburse us? It's been 3 weeks that I haven't had my car. And still no sign of it reaching me soon.
