till this day i never get my coin and never get any anwser from support from YOBIT
REAL DAME SUCK
OP isn't talking about bitcoin withdrawal but Universal withdrawal. It's an altcoin with the ticker symbol of UNIT.
To OP, I never experienced transferring an altcoin as Yobit as sender because of the obvious reason. Try to asked your fellow UNIT owners at their ANN thread and check if there's a same case. If none then you have no choice but to wait for Yobit's response. 4 or 5 days is still considered as short timeframe for Yobit's support to respond concerning altcoin withdrawals problem.
If you have BTC0.02 balanced their then you can shouting at their trollbox and hunt those board admins. It's kind of effective to some users. Or already accept that the funds were loss now.
