Did you see the message of the faucet which tell you how many tokens you get after doing the captcha? Sorry to ask, is this your very first time trying to claim the faucet on bitvest? If so, then I start to think that maybe you do not change your balance into token so you saw it as no faucet is credited. But if you are familiar with bitvest already then I dont think there should be any issues related to faucet.
