Fraser review: Absolute scam

Absolute Scam in my opinion. The owner placed an order for a much more expensive engine than the one I submitted an online quote for. When I called to correct (the next morning, before the item was shipped), he said the engine I wanted wouldn't arrive in time, and threatened to sue me for the price of the more expensive engine if a canceled the order, and also threatened a $400 charge for wasting their time. The owner, David Fraser, was literally shouting, saying his wife was a lawyer, and that he would love to teach a f* like me a lesson. Then, on top of that, he pulled my mechanic's name from the order form and proceeded to call them on another phone (while I could still hear them on the other line), trash-talking me, pleading with them to convince me to take the more expensive engine, and asking personal questions about my family (like whether they had enough money / could be convinced to pay for the engine instead). My mechanic called me and advised me just to take the deal and call it a cheap lesson in dealing with crazy people / not reading reviews, but after installation the engine doesn't even run correctly. The mechanic did their best to resolve all issues, but after taking the vehicle home I haven't even been able to drive due to constant misfires that I haven't been able to solve. One thing's for sure though, I feel like I'd rather burn the truck and roll it down a hill than contact their customer service and deal with their abuse again.
