I called back number 0450 379 024 reached voice mail but did not say for what company.

Returned a missed call (3 in quick succession). Goes straight to a telco "unavailable" message.
SCAM!?!?

scam , don't deal with these people

Caller: Claim to be from an online trading company

Scammer. Said they were from some online trading company. Knew my full name and said I had spoken to one of their reps in a shopping centre. I told them “no” it never happened, then they claimed to have notes about my discussion with their rep. Apparently I said I wanted financial freedom. And apparently this mob can provide me with that freedom. Hahaha ... nice try!

This number called, did not leave a message, so I thought I would look here. Blocked number.

I called back number 0450 379 024. It went straight to voice mail that was full and I couldn't leave a message. I sent a text but haven't got a response.
