this male named "Michael Anderson" tried to tell me that he was calling from Sydney and that he was from Telstra and that I had an internet problem

just saw the strange number and did not pick it up. Im on the do not call register.

So over these scams.

First call before midday, could not follow his conversation/Telstra working on internet phone line server, his English was hopeless so I asked to speak to an Aussie or his supervisor. Another person came on the line---not much clearer so I said this situation is hopeless.
I said my phone is with Telstra and internet with TPG, what do you need to tell me?. He said they would call me back they did and the conversation was garble so I ended it.

Overseas Indian pretending to be Telstra. Wanting all your information to scam you.

Clearly os call with delay but guy said he was from Telstra Sydney & that I had Internet issues. He said I needed to log onto my computer & he would help me clear the virus. I don't think so! Scammer!
