Caller: Claimed to be Telstra

Called from the mobile number. I answered and there was a delay in them answering. They said "Hello this is David from Telstra". When I asked what this was about, they said they were calling about my home internet (I'm not with Telstra) but hung up before I could answer.

Likely scam call spoofing the number as when I called the number back, said it was not connected.
