If they are still advertising courses on their website, then your friend should demand their money back.
I do know of two schools that have gone bust, the students have lost money, and then lo and behold, the 'directors' have opened schools in different names, offering the same training. Unfortunately its quite legal to do this.
It happens a lot in all industries, but lets hope its not going to be a trend in this one.
Im not saying that this is what is happening here, as there isnt even any evidence on the website that its closed down, however, it is so important to protect your training fees, as best you can. I think there is even an insurance policy to cover you for this, from Balens. If you are spending your hard earned money on training (or anything else), make sure you can get it back if things go wrong.
