I'm having a problem with some nitwit from Norway that keeps attempting to charge things, for unknown reasons, directly to my merchant account at my payment processor. Don't know why they're using my account ID but suspect maybe they're just scanning for IDs that will allow them to validate cards. It's always small odd amounts too, like $1.20, or $3.38, almost as if they were attempting to verify the CC is valid before defrauding it elsewhere for a larger sum of money without being detected too early.
I have all IPs to my merchant account processor blocked except those coming directly from my server, so they aren't succeeding, they are always rejected and declined.
However, the credit card processor is charging me for those declines, declines for transactions I'm not sending, transactions beyond my ability to control being sent directly to their servers.
I wrote to them today and asked quite bluntly why they were charging CHARGING ME for someone attempting to hack THEIR service, of which I have no control?
Has anyone else had this problem and how did you resolve it?
