Caller: Apparently Telstra NBN Tech

SCAM ALERT - These people were from o/s (I won’t be racist) they had names and addresses but did not verify who I was. I was told that over the past weeks there had been numerous attempts to access my nbn network and that they were there to help with this. They asked me to go to my tablet and download any desk app. They wanted to know my IP address so I gave them the wrong one, at this point I also questioned them about not asking me to formally identify myself. I challenged them to prove who they were to which said person put me on to his superior. I blasted him after he got shirty with me for asking too many questions. I hung up. I called Telstra and no such calls to me have been logged. Scam
