Gotta be a bit more forward thinking than to shit talk service when you have money still tied up in it sadly.
Thanks for the heads up though on behalf of the whole community. Not sure who owns gigabet or whatever but you can likely get your coin back if you either pressure them legally or knock their site offline until they return your stuff.
I'm not condoning or encouraging that you DDOS the bastards... But if you did it would be warranted imo.
