For months, CampBX has been having delays processing both deposits and withdrawals in USD. Many customers have reported waiting weeks or even months for deposits to be credited or withdrawals to be received. If you look at the recent posts by others on their
facebook page, you'll find many customers complaining about how long they've been waiting.
Opening a support ticket is the first action you should take, but you may have to wait days for any response and much longer before any problem is actually resolved. This is the primary reason why I withdrew all funds from CampBX in February and have not deposited there since.
