Caller: Scam

Male (refused to personally identify himself), but said he's calling from the Commonwealth Bank of Australia. Heavy Indian accent, very lound call-cenre background on the call (you could hear others yelling over the top of the call.) Said he's calling in regards to suspicious activity on my bank account - transaction of money to United States of America an hour ago. I asked him to identify himself, he refused. I requested he identified my name and my bank account number - he gave me some dodgy name (Marinka Sherika) and dodgy number that doesn't even match our bank account number count. Told him he's a scammer, and he hanged up. BEWARE!
