Reeves said anyone who has been a victim of fraud should contact Police.
"Keeping us informed helps us build our intelligence on this form of criminal activity which is very useful during our investigations."
Police will investigate any reports of fraud but it is particularly difficult to trace false social media accounts.
"Often, those selling these goods are using false accounts, appearing as honest and legitimate people," Reeves said.
"Prevention is our number one priority. If we can prevent people ever handing over money to these offenders, there will be less incentive for them to continue.
"Buy goods in person or through reputable sites, where you can verify that you are going to get what you are paying for."
The investigation into this case is ongoing.
