Caller: Apparently someone from Microsoft

Supposedly from Microsoft wanting to go through some hacking information on my computer and significant issues. The female wanted a Security person. It didn't get to the stage that they wanted control of computer but wanted me in front of computer. Stayed on long enough to get some type of story what they were trying to scam. Used the excuse that I was at work.

No one said anything. Potential scammer

left a message saying "hello" 3 times then hung up.

Calls, no message. Phone back. . Picks up, doesn’t speak. Then calls back again later.

If you call back you get a recorded Optus message to say the number was incomplete or incorrect.
