Caller: Online trading (probable scam)

A person called me from this number. I ignored it the first time and then they called again. Russian or eastern european accent and said I'd signed up to an online trading platform and they were looking to help be get started. I said i'd not signed up for any such thing and they said I may have through a pop up but I now had an account through my email. I said I didn't have time for a conversation so please send me any relevant information to my email address. She pressed and said we should talk first and then when she asked me to confirm my email address I hung up.

I called back number (02) 4243 7692 was put on hold music but no one answered the call.
