Update: My issue got resolved, apparently my payment address mistakenly got marked as invalid (maybe exchanger didn't support that certain wallet) but host answered me in PM and resolved my issue. They apparently contacted me on e-mail but I didn't receive any, maybe it got marked as a spam.
So no worries and sorry for the fuss, I did not want to make accusations or accuse host of disappearing, I was just a little paranoid. But host is active and paying.
Thanks for resolving issue.
