He rang me today and I asked him where is calling from. He claimed that he is from BG Trading (or some sort). I replied if I've contacted them. He replied no worries and hung up. Sounds DODGY!

Yeah talked about making money work for you. Something about Westpac. I said I don't want to and he hung up immediately.

Yes, I had this bloke call me as well claiming I can make money on sports betting. This is a scam listed under the scamwatch government website. Just tell him to get lost

This number offers you an opportunity to make money from home. When you respond don't think so he immediately hangs up
