Yes I don't know deposit required before withdrawal, they updated the terms on recently (sep-2020), I'm not active online while lockdown in India.
If your withdrawal time was after that update then I think that's not their fault in the first place but at least they should have put a warning that faucet satoshis shouldn't be withdrawn if the user will not deposit first. If they can't be withdrawn then how come it let through even in the first withdrawal?
