Scammers can fake caller ID, name tags, receipts, and email address information which can trick people into thinking that they are legitimate. If you are ever asked for personal information or feel unsure about a call, you would want to hang up and call the business yourself to make sure that it was legitimate. These same general rules apply to emails, if something ever seems weird, or you are being asked to pay in a different currency, please contact the business directly. You can find out more here,
