Somebody rang so many times without leaving messages and finally left a message not telling where she is from and did not even address my name correctly and asked me to call back. Looks like it is debt collector according to other people's comment here. I have been receiving debt collectors' calls looking for someone else. Even after telling them so many times that I am not who they are looking for, I am still getting calls. Should I call Police? What can I do? Just keep ignoring??

I called back number (02) 8651 5304 spoke to a guy but did not say from what company.

Debt collector, very harassing, borderline stalking.
I know this because they called me to ask if I knew the whereabouts of my cousin.
