I received a call from this number, it was a recorded message stating they were from Voda Phone and my phone has been used in an unusual manner and I will be shut down soon
They then asked to press a number to be connected to their service department. Of course I disconnected the call.

Given we are with Telstra definitely a scam call.

Called a business phone stating "Your phone will be disconnected in 2 hours". If your phone service will be disconnected/disabled, your provider is more likely to contact you via email, if at all.

I just received a call from this number saying it was from Visa & Mastercard fraud dept. they said i had 2 amounts taken from my debit card. An $11 amount from Netflix & $800 for a florist. If I dont recognise these amounts press 1. I hung up, checked my account which has no such transactions on it.

The automated female caller speaking Chinese (I think it was Mandarin) left on my message bank. I don't know what she said.

Caller: (02) 5303 1580

Saying they were from DHL and were going to return my package. Scam

I don't know this number so didn't answer. I assume it is a scam caller as advised above.
