I'd remove all the money on that card and never use it again. If it's a reloadable card that you get paid on, I'd call and report it lost and get issued a new card number. But regardless, I'd be going to an ATM and taking all that money out asap if you can. If you gave that number to someone on FB, I'd be concerned all your money is already gone.

In the US, this is untrue. CC companies do provide vantage scores on your statements though because it's cheap to do so. But in terms of credit decisions, FICO is used the majority of the time (there may be a handful of lenders that use vantage scores in credit decisions. MyFico forums would have this information).
