This number has been calling me all week. Today, have had no less than 5 calls from this number as well as (08) 6733 7431, (08) 2683-2492, (08) 5913-8059 and (08) 1164-4943. I believe they're linked. Easier to not pick up landline calls at all. I'm making a formal complaint, as these calls are a daily occurrence.
