XVG appears to be listed as DogeCoinDark on YoBit.

Not able to see that YoBit lists Verge on here though.
Supposedly DogeCoinDark is the previous "Verge" before it being rebranded.

You are not the only one with wallet problems though, I have a few bitcoins worth stuck in Decred/DCR and wallet has been under maintenance for a few months now.
They've recently said they're going to fix the wallets in the next 2 weeks... hopefully they manage to do it.
They handle quite a lot of coins (almost 700 I believe) so mistakes are bound to happen
