Called me yesterday and today but I didn't answer and they left no message

(02) 8231 0775 has called on my mobile five times in the last three days. Twice yesterday and twice today. Of course, never leave a message. Anyone else received calls from this number or does anyone know who it might be?

Called twice 1 immediately after the other but came up as suspected spam so didn't answer - they left no message. They did the same 2 days ago. Will block now after reading the comments listed.

Consistent calling. I picked up today and they hung up

Called at least 5 times in last two days, never left message. Believe this a scam call.

Called twice a day for the last three days. no message left.
