I too am awaiting a refund of my flying account from EFT. I'm in two minds though whether the legal / CAA route will have the desired effect.
The way I see it, the only way that anyone is going to get a refund is if EFT continues to operate as a business. Pursuing legal action is more likely to push EFT towards closing it's doors. CAA action may do the same. End result in both scenarios = Kiss goodbye to any refunds.
I think EFT is a good school, but has been through a rough patch recently, mainly due to issues outside their control. I was reasonably happy with what I received at EFT. The instruction was of a high standard, and although I didn't fly as much as I thought I would, it was still a lot of fun.
I am still hopeful that I'll get my refund, I hope I'm not proved wrong.
