gold base also reselling base dude, i got dead cards with code 2 and said no refund
but code 12 means - Incorrect card number -or - The card itself is invalid or - Expiration date issues - or - Strange activity - or - Multiple transactions in a row - or - Address verification service error
so, its very clear card is used somewhere with many txns
