I think it is from Australian Stock Report

No message left. If you ring back you go to a voicemail system that says you have reached the mailbox of 2261 and to record your message.
No idea who it is, and they obviously have no idea of time either given that they rang at 3am in the darned morning!

Hung up when I answered. May be related to series of calls from mobile numbers saying they closed my bank account. These calls started soon after this call.

guy was telling I sent him apparently an Email and enquiry regards stocks ..I responded do not recall sending any emails. I am not interested, and finished the call.

number unknown to me
