Called back, it was a company called "fleetcore" or something - they sell fleet fuel cards. I think the strategy is to call you and hang up, then when you return the call, the sales person says "maybe it's fate that has put us in touch". Lame.

I rang back the number (02) 9188 3035, spoke with someone who hung up right away

Caller: 91883035

This caller phones me a few times every morning - they are labelled, so the call won't be answered, but it's a nuisance that all my synchronised phones ring anyway.

Caller: Fleetcorp

So far have rung on 10 different days from 9 different No
Don't answer there calls, If you do hang up........

Ring everyday and soon hang up.

called me twice in one day - I don't know anyone with the 02 area code. So I left it unanswered

Caller: Fleet Corp

Car rental sales person
Wouldn’t stop calling
Block them!

have received about 5 calls , I dont answer but it hangs up after 3-4 rings anyway.

As soon as you answer they hang up. Multiple calls per day
