Not upset, just disappointed

Took my car there 3 times. Long story short, I paid a fortune, my gearbox is leaking oil after a full recon, they broke my transfer case and fixed it with JB Weld or Pratley Putty so it can last for the warranty period of 12 months. They are the only people who worked on the car in the past year and after I queried about my transfer case, they denied everything. It seems that no one owns up to their mistakes anymore, much easier to lie their way through.
