Caller: Charity

I get about 2 phone calls a day from 03 7073 xxxx numbers. If I don't answer, they never leave a message. If I do answer, sometimes it hangs up. Other times, after answering, it ends up being a charity after donations. Even though I ask them to stop ringing, they keep ringing daily from a different number every time.

I received a call from this number (03) 7073 0491 and it sounds like an indian male stating i made a claim of some sorts?
