This is very rare, but it is possible to have a negative amount earned since your last month's payout if a chargeback has occurred. In cases like this, a customer has notified their credit card company of a fraudulent charge to their account from your Job-a-matic site, usually when their credit card information has been stolen and exploited. The credit card company then withdrew the money from that charge to refund the customer. However, if we have already paid you for that original charge, your balance will appear as a negative.
