Unknown number, no message left, = no call return.

A lot of background noise somebody kept on saying hello but would not answer me

Noise, busy background. Asian accent, said they were from Telstra and something about a virus getting into our computer and phone line...sounded like scam. Hung up. They rang back! Hung up again.

This number has called me 11 times in the past three days!

scam call claiming to be Telstra tech support.

Caller: Reckon an unsolicited spam call

Long pause, noisy background, said they were calling from Telstra (2:30pm on a Saturday...really...). I hung up and blocked number.

I rang once and got disconnected
