yes, I've seen cases before here in the forum where the gambler is complaining about their withdrawal getting delayed for a week but those cases usually have other reasons as to why the withdrawal is delayed. in your case, they mentioned that +20mbtc withdrawal could take some time because they need to check to make sure no foul play happened. anyway, just to be clear, I am not siding with them, I am just saying what the reason could be for the delay of your withdrawal.
