This needs so much more traction, because soo many people fall for stuff like this. I also work with fraud calls, and my advice is always this: NEVER call a number given to you by a caller or in a text/email message. ALWAYS call the number on the back of your credit/debit card, your bank or financial institution printed it there for a reason. Use that instead of anything given to you by someone else, no matter how legitimate they may have seemed.
