If you see a transaction in your transaction history that you do not recognise, please consider the following-
are you in possession of your ring?
when did you last use your ring?
time and date of the transaction - where were you?
could the retailer be registered or trading under a different name?
is the amount a familiar sum?
did anyone else have access to your ring at the time of the transaction?
