They never leave a message and use every combination of numbers for the last two and are constantly calling me from these changed numbers - I block everyone number they ring from!

can receive up to 10 calls a day. the last 2 digits change with every call received. so it's always (02) 7251 25XX. i never pick up.

Continuous spam calls MULTIPLE times a day!
I'm already blocking every number that comes from "(02) 7251 ***" but I can't keep up with them and now this prefix has started as well!!

(02) 9071 0075

I'm an Optus customer and NEVER had this many spam calls when I was on Telstra and every time I speak to friends about it, the first thing they say is "I bet you're with Optus" - is our number on sold list or something?? There's no point even moving away from them either as my number is already out there now. I've had this number all my life and use it for work as well so I can't change it.

They've Called for a few days and the person I talked to told me it's about an educational course which makes money. When I told him I'm not interested in it, He's getting aggressive and didn't listen to me so I terminated the conversation and blocked the number.
