Caller: I can never get their names for this kind of scam calls

Kept calling me everyday until I answered one time. A wonman said she is from chasy something, I asked her to repeat the name again but still couldn't catch the name, so doggy. She asked me whether I am working and under the age of 40, I said I am a student, then she said no worries, bye.

I have no idea how they got my number and name, this is really annoying as I get this kind of calls very often, they just keep calling until you answer. I have blocked at least 20 calls.

Ignore this rubbish number

Caller: Chase something...?

Several calls received, this one I answered but didn’t get their whole company name

I called back number (02) 9137 4206 reached voice mail but did not say for what company.
