Wow, the third one sounds like something out of a horror movie. You certainly have grounds for a complaint, but first consider whether any complaints procedure would be retraumatising for you. You have to put yourself first.
There are good T's out there, but unfortunately sometimes finding one isn't as easy as it should be. If it's possible in your area, you could try looking for a T with specific experience/specialism in trauma plus lots of years in practice. I would also avoid CBT therapies and similar.
Good luck in your search - you deserve much, much better.
