Sounds like you were very unlucky.
If you let me and other pprunes know what part of the country you are interested in training I am sure you will get alot of suggestions.
I did my PPL at BCFT (Bournemouth) and would recommend them, but I am sure you will get a lot of other equally good recommendations, and possibly quite a few cautionary tales.
Don't be put off by one bad experience
Good luck
