they are thieves, do not believe gatehub, they are deceived !!! day, the cue ball will be credited (on the course, they rent accordingly), 50 coins are taken away (for a purse and not 20), and this is 50 bucks ... instead of 292 coins bought by me, only 228 were transferred. Do not get fooled !!!
use the norms of the exchange, this bottom!
Even though I've never really delt with GateHub I do have to say a lot of the companies in the crypto space right are plagued with new people, so you're going to have cut them some slack cause they can't handle the amount of people who are using their services right now.
I'd send in another ticket, try to call a number if you can get to it and wait. That's all you can do. Worst case get some regulators / police involved from your own country.
