Caller from Port Hedland - they didn't leave a message

Tried to tell my they were from Telstra and are ringing about my internet connect. Funny thing when I said I don't have internet he didn't know what to say. I hung up.

I took the call without speaking and they immediately hung up.

Another nuisance call! I don't answer our land line any more. All calls divert to my message bank. No message left... they just hand up!
