Zero customer service and ignoring my refund request

I attended the free seminar and stupidly signed up to the paid 2 day course that was 'half price for today only'. I later found out that the course is not even run by legacy education alliance and the full price of the course is 1/3 of what i paid at a supposed 50% discount, so in other words, the usual price that legacy education alliance charge is 6 x the actual course price. I requested a refund based on being misled and lied to but they refused and are ignoring my emails. They don't answer the phone so it is my only method of contacting them. The have since cancelled the course that i was due to attend and still have not refunded me. This is appalling. Do not throw money away with this company - they are not to be trusted.
