10 years ago decided to do my C+E with the training arm of a very large car dealer in Glasgow…
Paid out similar amount to OP, instructor was so pathetic. Couldn`t stop talking about themself. ( notice how I never said himself) & their skills as an instructor were (zb) poor. Got licenses in TA apparently 
Anyway was getting nowhere in jacked it after 2 days despite remonstrating with very large Glasgow car dealer company. Lost money & desire to ever do it again. Been doing class 2 ever since & quite happy 
Should`ve hung it out but i have a total intolerance to incompetence.
P.S not …ist in any way. Incompetency comes in all forms.
