I think it comes from the same place as two other numbers from the suspicious numbers list: 03866438000386610300, but don't know who they belong to.

Me too. It's peculiar and annoying.

Keep getting calls from this number but don't know who it is.

I think it comes from the same place as two other numbers from the suspicious numbers list: (03) 8664 3800
(03) 8661 0300, but don't know who they belong to.

I called the number back. A voice recorder service answers & says "Hello, this is Telstra. We recently called you to talk about our products. If you were'nt able to answer then we'll call you back soon..waffle waffle"

Call Telstra Nuisance Calls Dept and ask to be removed from this marketing list
