Worst Customer Experience and ********* behavior from the Manager

The Imperial Select in Tokai has the worst Branch Manager ever (Duncan Scott), he will do everything in his power to get the client to pay for things they don't have to pay for. My fiance took out a car from that branch, 3 days later, the car broke down while it was being moved out of the driveway, they took the car in, apparently the timing chain was broke. He came up with what he termed as the only 2 ways this could have happened(which were basically implicating that my fiance is at fault for a timing chain that broke while the car was being reversed out of the driveway, 3 days after she took the car, right??), which I argued with him, and gave him a different possibility of how this could have happened, and instead of listening to that, he still pushed on his "theory" and wasted more than 2 weeks trying to find a way to make the client pay the damages on this car while he knew the dealership has to pay for the damages which after all that waste of time, the results where, I was right all along. After that when my fiance threatened to pull out of the deal, he made up a non-existent clause in the CPA(where he said if the dealership can fix the car, then the client HAS to choose that option of fixing the car), which I verified with my legal adviser that it's incorrect. They offered to give her a loan car while they fix her car, now he says the loan car is returned with what he says are mechanical problems with the car my fiance drove for about 2 weeks while her car was being fixed. At this point, he is again trying to get my fiance to pay for these damages and when I went to speak to him, threatened me with a lawsuit, and chased me out of his office because I was calling him out on his ********* behavior. He is basically trying to get my fiance to pay for whatever mechanical problems the car has even though there's nothing he has on the table that says whatever damage this loan car has was caused by the driver. Didn't even try to see if it's a wear and tear issue which would have happened with any driver driving that car, instead, his 1st response is to try and get the client to pay for it. I have never seen such customer experience, just totally *********, if you ever buy a car from these guys, just know, whenever anything goes wrong with your car, that's the kind of experience you going to receive from that Manager, I wanted to give no stars, but unfortunately, you can't do it here.
