Caller alleged to be from Telstra technical department. He alleged he was calling because they had multiple reports about my IP address & that it was changing from private to public. I was driving at the time so the call came through the car audio system. I told him that I was driving & he wanted me to pull over & use the internet on my mobile phone. I told him that there was nowhere to pull over. He asked when I would be home so he could call back. I told him that I was not sure but it would be several hours at least. He said that he would call me back the next day. When I got home I checked my mobile it registered the call as Suspected Spam. This confirms my thoughts that the caller was a SCAMMER.
