Caller: JCU

The call is from James Cook University about course enquires.

Caller: She wouldn't say.

Asked for someone with a man's name. I said you have the wrong number. She insisted that she had my number as a contact for this man. I asked who she was and she wouldn't say. She then asked how long I'd had the number for at which point I replied that's really none of your business. She continued speaking but I hung up. I suspect either a scammer or debt collection. She didn't sound very bright.
