Good luck. I pulled out of a course 3 weeks before it was held, and called to tell them. I called again when they invoiced me 2 days before the course, they then tried to say I hadn't let them know in time, they hadn't got the message, they had nobody called Louise working for them etc etc.
They were very dogged, sending me more invoices then threatening letters re suing me, which I filed neatly in the round archive.
Total numpties - I am still on their mailing list and still get junk mail from them.
Anyway my point is that training companies tend to have this kind of thing all sewn up, you will no way get your money back. The key is to not pay until you are sure !
