Received a call from an Indian caller telling me he's from Bank Security. Told me there are charges on my account and they have intercepted them. Scarily, he gave me my previous address and said the charges were coming from there?!? I asked him a question, he told me to hold on but go to my internet banking. I hung up at that point

Number from Melbourne. I picked up the call and purposely said nothing (spam callers generally want to hear a person on the other end). They hung up fairly quickly.
