Love paramotoring, but instructor is a bully

I started this course full of passion and enthusiasm for paramotoring but had to quit due to Steve Haze acting like a bully during this course. Let me start by saying I already have my Private Pilots License, ran the London Marathon this year and climbed to Everest Base Camp 2 in Nepal. I'm not super fit, but certainly can handle myself. Steve Haze told me on the second day of training that I would not have the strength to do it when one hand control of the wing ripped out of hand during ground handling. I told him a massive gust of wind hit it and pulled me off the ground, to which Steve said "Can't fly then, you won't have the strength to do it". Another time he said "It makes me very angry you appear to have forgotten what we learnt last time". I can handle a light joshing, but he was an outright bully and an older man on the same course as me complained to him after he had experienced similar "joshing”. I am currently reviewing legal options as it makes me very sick that he asks for the whole fee, nearly thousand pounds, up front which gives him no incentive to be a good coach at all. Tread carefully and think it through before parting with your hard earnt cash.
