Went to my message bank. They did not leave a message. They tried a second time which also went to message bank.

Caller: 'Telstra"

when we heard the voice saying they were from Telstra, my husband yelled out in the background ' SCAMMER' the person then said 'get lost - shut up' & hung up

Caller: Someone claiming to be Telstra technical

They advised they provide all service lines for all providers so it did not matter I was not with Telstra. They wanted to know if there were any problems with my computer screen, when I told them I did not have a PC they hung up
