Sugar Road Tyre & Mechanical

I asked them to replace a timeing belt 2016. As this is standard mainetance work I am aware that my 4t truck is not standard in AUS. It happens that the timing was not correct and the motor got damaged. In my case all pistons hit valves, it has push rods, so no total damage.
But now the facts I cant accept:
- Returning vehicle damaged (mechanical noise and smoking heavely)
- trying to blame me to leave an old truck for them to repair
- initially not willing to refund the money for the unfinished job, insurance later paid
- leaving me searching what could be the cause, timing check and the somewhere else repair. I could not trust them to repair it.

So after all, friendly guys, good price but they might be more specialised on tyres.
