Caller: I’ve got no clue but they know my name.

This person called me saying they though it was their brother’s number, and why my number was coming up as her brothers contact. She said my full name and asked if that’s who I was, and then she introduced herself as if we had known each other for a long time. I asked how we knew each other as I knew no one that went by her name, and she refused to tell me. She asked me to tell her my brothers name but I don’t have a brother and she said “well then you aren’t (my full name)”. And I said I am, and I think I would know if I had a brother or not. She abruptly hung up after that. The number is ‭0432 161 303‬, and needless to say, I’m very confused.
