Caller: Telstra (apparently)

Female voice calling regarding our internet service. I asked if I can call her back. She hang up.

Caller: Apparently the 'Technical department of Telstra'

The Indian accented caller requested to speak to the internet account manager, I asked what name they had for that contact and they did not provide the correct name (wrong state even!) so I informed them they had the wrong number and we ended the call.
