attempt buyer buyers cares claim commit evidence fraud likely log logging lying order ordered receipts remorse route sales thank-you trace track type

Is it possible to have complete IP logging into sales receipts... I have a person
saying he did not order, I see no evidence that fraud was commit, more then
likely or ordered then had buyers remorse or something...

without some type of IP logging to trace the route, i cant tell or have any evidence
to back up the buyers or my claim...

Thank-YOu

no one cares about this, is there a way to get a log from a buyer using e-junkie?
I could use this to attempt to track the buyer to see if they are lying or not.
