No refund of payment promised

I made a booking for my son to attend a camp during the upcoming school holidays and received a confirmation of his attendance, payment was made when I received funds only to find out that the camp was cancelled without me being notified, or I wouldn't have made payment.<br> I was asked for banking details to do a refund on 12 March 2015 which I provided, to date I have had NO feedback from TOPSchool of any form, no replies to my emails or refund of my money.<br> Totally unacceptable, not even the phone is answered or a facility for a message to be left.<br> Just want my money back NOW!
