Caller: Pretending to be Telstra

Called, and then called back again immediately which I answered.
Caller said she is from and they said they are giving me 50% off my next bill and asked me to confirm my email account. I didn’t. But as soon as I hung up, someone tried to log on to my email account and I denied the multi factor authentication. Don’t answer.
Not co-incidental.

Blocked this number, but it called me again 3 times.

Called 3 times in a row but I did not answer, they did not leave a message

Caller: 0497 628 637

Repeated calls despite declining to answer. Lady with Indian subcontinent accent claiming to be from Telstra and offering 50% off my next bill. Hung up immediately and was called immediately twice, again despite declining the call.

Same thing called twice so I answered, said they were Telstra hung up and they called 2 more times

Called advising they were from Telstra, providing 50% off my bill for the next six months.
I ended the call, and they tried calling back two more times, each with no answer.
