Caller: They called, l answer reluctantly, with them saying its Telstra

Now, l cant be sure this is the number, as my phone, seems to only have the (02) 773 6143, but l felt it was from Sydney, with this person calling on other numbers l refused to answer over 2 days of hourly calling.
They claim that l had an issue, with my internet connection not working, yet l not with Telstra, and they wanted me to access my PC, but l questioned them, and stated l had no problems, but somehow they knew my surname, l made out it was not me, and l hang up. Very concerning.

Other numbers l believe used, with the last 4 numbers changing only were 6143, 6141,6175,6161 and 6188. l bet they have more, will see what numbers are tried tomorrow.

But if the number has no 9 in it, its possible to be a scam done from India, as thats who they sounded like, definitely Indian. Be careful.
