How to avoid being scammed...
Hang up on ALL cold callers. If you are worried that your bank really might need to talk to you, put down the phone and call it using the number on the back of your bank card or on its website.
Remember banks will NEVER ask customers to move money to another account to keep it safe from fraudsters.
Never disclose personal information even if the caller sounds convincing and appears to know personal details.
Never respond directly to unsolicited emails or texts.
