LDR Engines And Gearboxes Pretoria

I went to Pretoria bought the engine and payed the money for courier, the engine was wrapped up and I was sent photos and I was told that it is just waiting for courier to collect. Day after the engine is on it's way, was very impressed only to find out that the engine is NOT the one I bought, when I asked I was told that the one I bought is not the right engine for my car but it was the right one before I payed. Now I was told that I must fit the engine if it doesn't work I ll be given more parts to fix, and the reason why I wanted the complete engine is because I didn't want to fix the old one. I am very disappointed with the service I'm getting as a first time customer, I wouldn't recommend it to anyone even the stranger.
