Item purchased low value ($150) card transaction OK. Item sent to listed (Sydney NSW) address returned to warehouse as no such address exists. Phone number listed invalid. Further check many variations of this bogus entity on line. Further investigation - reveals that data entry to our merchant web site appears to have been some form of computer script, so not input manually by buyer.
Check using Geoiplookup.net shows Ip of computer used to lodge order in Fremont USA (Calif). Clearly suspicious - distance and country plus item bought uses 240Volt AC rather than US voltage. Awaiting chargeback from actual cardholder.
