It seems like support from yobit is too bad. I will be staying away from yobit. Do you have any good feedback with other exchange? Thank you for taking time to response to me.
I needed help from Poloniex support back in 2017. They didn't answer my ticket, but the problem was fixed within hours.
I had tickets at Bittrex. The response took weeks, but it was
not urgent, it was
not about money locked, in a way or another.
I had ticket at Bitstamp, again not urgent, and it was answered in about one day.
The problem is that all these exchanges need now KYC, so they are out of the list you need.
