My first instructor was from BSM so i just assumed they would be professional (WRONG!!!), my second one was private and had his green badge. This did not stop him failing to show up for a lesson one day then never answering his phone for weeks. I had paid �100 up-front for lessons so was a bit annoyed, then I received a post-dated cheque dated...wait for it...Christmas Day!! My third and final instructor was fab and swiftly got me through my test first time which was nothing short of a miracle ;)
