Keeps ringing me but cant call the number back noone answers

I'm pretty sure this is "Spin Palace" the online casino.

Scammers.

Will call from (02) 4329 2219 followed by (02) 8599 2180 soon after. Never leave a voicemail stating who or why they are calling. Something to hide,scam....?

Had a missed call from this number - called it back and a recorded message greeted me with "hold the line" and then someone answered from what sounded like a very busy call centre and said "Promotions how can I help you". I hung up.

Rang someone else asking for me..do tried to call them on the number they rang them on and couldnt get through.

I called back number (02) 8599 2180 just kept on ringing no one answered the call and never got any voice mail.
