Reading what people say about mercatox, those who criticize say that they are taking advantage of people, keeping their money there without the right to withdraw. Those who defend her say she is very lazy.
Putting these two analyzes together, you deduce that you will only get what you want with this exchange if you react to its delay in some way, in chat, by email, or by reporting it. I also noticed that by email the solution was better than by chat.
My recommendation is not to put doge in mercatox until everything is resolved (they don't want to take the deposit). I thank the members of the bitcointalk forum who tried to help me in their own way, in the end I don't believe that your action really reached mercatox, but I thank you for your good intentions. As well as those who shared and reported mercatox with me on twitter and reddit.
Reading you case, i will still not trust mercatox even though your case was resolved. A good exchange will usually resolve the issues then and there and would not delay and frustrate their users.
I would say that you were lucky that you got your funds withdrawn from mercatox. Since this issue is now resolved, you may lock this thread.
