This number (02) 8583 3566 has been calling me consistently every other weekday (alternating afternoon / evening) for the past 2 weeks and I really want it to stop. Does anyone know how I can disable this number from contacting me?

Said they were from iprimus and wanted me to sign up to the NBN but he didn't know if my area was NBN ready or not. Sounded like a scam. Hung up before they could get any info from me.

Just save the number, then block it.
