Called regarding currency trading - cold call spam

Unsolicited call from BM Consulting or something like that. Asked if i was interested in learning how to trade online.

hung up on answering

Caller: (02) 4672 8624

Same here, called me right now but i answered without saying any greetings and put my phone on mute right away to hear any clues on who it must be. The person didn't utter a single word or hello but i could hear other people in the background. I wasted a good 10 mins of the caller by keeping him engaged on my call. I then dialled the number after sometime from a different landline and the number is out of service. Scumbag MOFOs!

Called and no voicemail left
