I sold few coins on vindax that worth 10$ and I don't receive any in my wallet after withdrawal, I track transaction ID on etherscan and it says 'Failed', then I head to their telegram group to complain, guess what happens next? I was told to deposit 60$ worth of Eth to an address from a PDF, I screamed scam and they block me off their telegram group, here is a screenshot

All vindax exchange team are scammers, you've been warned, stay out of this exchange at all cost
In my own opinion, you supposed to talk or to inform your issue at their support of Vindax to their exchange platform, not in
telegram channel, because they're not making chat to anyone via telegram. I think your not aware of this
things dude.
