Off-topic quickly, but I just checked them out and they have a very limited offering and I've never heard of them before, so I kind of wonder if they have an established reputation.
They have been in operation since 2014. Probably one of the few old exchanges left that refused to introduce KYC on their platforms. They only became more reorganized recently when they started a signature campaign. IMO, I would trust them more than the like of Changenow, Changelly etc.
I saw the status of the issue on BestChange. They (Changenow.io) claim they have refunded OP his funds. It would be nice if OP came around and updated us.
