claimed to be telstra very noisey background

I missed the call. When I tried to call back there was a recorded message saying Optus advised he number was disconnected. Interesting the message was from Optus given I'm with Telstra

Didn't leave message. We let calls we don't know go to the messagebank.

No one answered when I picked up phone.

Call Centre - you could here them all in the background

Foreign accent claiming to be from Telstra
