Disgusting, common *******

My car broke down in the northern cape 8 hours from where I live ,the engine needed to be replaced just over 1 month of buying this car from a dealership and taking a vehicle finance loan from the bank,which I still need to pay for the next 5 and half years,this car has been in northern cape since January, remtec wanted half the deposit to build an engine which they took in June , knowing that company is getting liquidated and still ******** money from people,last communication via email was 24 June saying they waiting for parts,the workshop where the car is was communicating with them but they were not answering emails nor calls,I tried calling the phone just rings and says the number is not available,so I started reading reviews when I saw that they have done this so many people,I'm so disappointed, disgusted, heartbroken to know that these people behave like common *******,I don't know what to do ? If anyone knows how to resolve this? Anyone can help me information,it will be greatly appreciated.
