The Point is, they advertise everywhere NO KYC.
And than they ask for 30 USD for KYC?
What does with the Coins happen when I dont agree to do KYC? They keep them.
Maybe it's the rules of coinswitch.co to do KYC if you want your coins to return right, if they really advertise without KYC anywhere you should ask first to know everything.
So I think the only way is to do KYC if you want your money to be returned.
Got your point however this should be on their Terms of Services and it should be clearly stated.
Likewise, what happened to OP is clearly crossing their ToS.
However, basing on your conversation the transaction was automatically flagged by their system, would you mind giving us exact scenario aside from transferring $30?
