Hi! Got a missed call from this number. I rang and she said it’s from TSA. She said it’s regarding a recent order from Telstra. Asked for my name and date of birth. And she puts me on hold. I hang up and got in touch with Telstra support and they said: I am not sure if the number is associated with Telstra because we don't have any information regarding the numbers our TSA's use. So I request you to collect the device if you get a call from our delivery executive.
