I've tried complaining to Telstra about this number and a lot of other numbers starting with 02 8415 85** last two numbers always change. I've been getting daily calls from these numbers - no one speaks and sometimes don't wait for me to pick up phone. I have deduced that they're generated by a computer and probably linked to an online scam that nearly cost me a lot of money in fake SMS messages that were being billed to my phone. I say complain to your telco but don't try to call the number as I would worry that they may find another way to scam you or keep ringing your phone. I've seen a lot of complaints about this practice from these 0241585** numbers - unfortunately our telcos can't seem to keep up with the scammers!

I am keep receiving call from (02) 8415 8592/49/91/96/47/04/33/16/57/, they are so annoyed!!!

Same here. calls becoming more and more frequent but the last two digits are never the same. How do you block these?

I usually get 2 calls a day from these people. I've had enough.  I wonder if there is anyway of blocking them (on an iPhone)?
