Caller: Mystery Shopper?

Caller asked if I wanted to be a mystery shopper - have a consultant come an discuss tax benefits available for home owners.

Hung up and blocked number

Claimed to be Telstra security wanting to check my internet but very unprofessional very pushy. Indian accent be wary.

message was left on my answering service could not make it out as it was very distorted but it was a woman and it sound abusive has anyone else experience this and rang number said it was with optus and disconnected

Received a missed call from this number but when I tried calling back, its the usual "number you called is disconnected" prompt so blocked this number straight away.

Still connected because just rang me. No message left.

I called back from a private number several times and it was just engaged

Recalled number. Telstra and Optys have recorded message saying this number has been disconnected

Called back for a message from Optus saying that the number had been disconnected
