I'm reasonably new to ecommerce and have what I feel may be a possible fraud but am not sure what to do.
I currently have my transactions set to deferred as I wanted to make sure possible frauds didn't get through and hit me with big charges and I have what appears could be my first instance.
mobile phone number
billing address different to delivery address
IP numbers on my stats do not match transaction IP number (AOL probably)
What the main issue is though, is that the customer, Jason, first tried to purchase with a woman's debit card - different surname and from billing address A in Town Y.
This transaction was declined by the Acquiring Bank.
Then, about an hour later, Jason tried successfully to use a different card - again a different name from a man at billing address B in Town Y.
The CV2, address, and postcode all match and 3rd Man results say OK but it looks so dodgy to me.
Should I just abort the transaction and forget about it? Or should I contact the customer via email - but say what?
