EFL instructour - Recensione dipendente - ESL Instructor presso Education Experts

I signed a contract on an Open Day in June 2014 and subsequently paid £500 to secure a place of work. They agreed to refund me In October 2014 but never did. I filled in a refund form which they accepted decreed the refund date the 24th of October but never did. They ignore my emails and phone calls. What should I do to get my refund back?
