Caller said they were from Telstra offering 40% off mobile phone bill. Proceeded to ask for personal details so I closed off call. Called back from another phone number that came up with Telstra ID. Also received one time code text to my phone. Same offer on second call which I also hung up.

Caller: Scammer

Caller said they were from Telstra offering me 40% off my bill. Said I was with Optus and the caller then said they were from Optus before laughing and hanging up
