Engine Source Bad service

I recently bought a G4FA Hyundai Engine from them and from the start it was just a lie where the engine come from and the condition of it. When I told them there is a problem on some of the parts they requested photos but still till today no feedback. The Engine also came from a different suburb then was said and I had to pay courier services that were not supposed to be on my account. It was said I must pay and they will refund me later and still today no refund the services of them are very poor please don't end up in the same trap.
