Changed from Aeros UK
I was with Aeros flight training, they messed me and well most people around and took money from our flying accounts without permission. I left and went elsewhere, best thing I ever did, others stayed and ran out of money with half a licence and another guy took over a year to do his IR as they keep fleecing him.
Life isnt perfect and employers know that, just have a good reason of why you changed if you are asked at interview but it probably wont come up.
Good luck!
