Bad quality truck

I bought a new rollback truck from Danau Auto end of July 2015 .They promise me the best service and a good reliable vehicle As from the Saturday I drove away from the dealer ship I experienced problems with the truck .Speedo not working I phoned the salesman from who I bought the truck he give me the cell no for the mechanic and asked me to phone him for assistance .When tilting the cab we discovered some serious hydraulic oil leaks on pipes A PTO PUMP and tank fittings. They sort that out and two hours later I left Pretoria to Standerton. Four days later we found that the main hydraulic cylinder are leaking oil very badly .I took the truck to the nearest dealership and they were very help full and explained they cannot assist but arrange with a hydraulic expert to assist me.The following week I took the truck to them and they did the repairs ,but send an email to Danau Auto and told them that the cylinder are damaged when manufactured and needs to be replaced. The paint work on the flat deck on the truck are also bad workman ship and was reported to the owner of the dealership. They refuse to assist me .I want them to take this truck and will buy one from a other dealership
