Woodard Auto and Truck

I took 2 cars to Woodard, a 2002 Ford F250 that they replaced a fuel line on (rather expensive but polite and friendly so I didn't mind) then I also asked them to take a look at my 65 Mustang that was had a T5 Tremec that was stuck in reverse
Short Story I would have been better off going else where with the mustang.
They picked up the mustang and started it, it started right up. So they take it off to the shop and 3 days later I get a call that its just the shifter that broke so I buy a new short throw shifter and have it mailed to them. I get the call the mustang it ready and I go and pay, later in the day they are dropping it off at my place and the tow truck driver forgot the keys to the mustang. I said no worries I will follow you back to your shop and get the keys so you dont have to make two trips. I do this and everything seems fine. But when I get home and go to move the mustang from the street into the driveway it wont start. It sounds like the starter isn't engaging and is just spining free.
I called back to ask what happened and I am pretty much just told the guy who worked on my car is 67 years old and he knew what he was doing. After they told me they had to rock the engine to get it to start in the shop, and that they had issues with it in the shop. Which they never mentioned to me once until after I complain that it isn't starting. I asked why they were starting it and messing with the engine if they just needed to replace the shifter and I am told he is no longer going to deal with me and hangs up.
I also was told he was on vacationt the week before and now the guy who was here last week is on vacation, I asked if that was somehow my fault? Does the client need to check with them to see who is on vacation and when before giving them work? Do we need to watch your schedules?
This mustang would start without issue before they touched it, and now I have a serious problem that will cost me twice the amount as the original repair... DO NOT USE THEM UNDER ANY CONDITION!
