Rang me 4 times in a row whilst on another call. Finally left voicemail, not giving me his name or reason for calling. Just asked that I call him back.
This guy has an Australian accent!

Claims he was from Peninsula IR but when I asked him to email me his questions he hung up.

Scammer

Caller: "Sam, from Peninsula Australia"

Called 2x
My outgoing voicemail message says "leave name, business calling on behalf of AND REASON FOR CALLING"
"Sam (Asian voice) call me back please"

I texted, "sorry Sam, unless you tell me what the call is about in your voicemail I will not be calling you back"
Let's see what happens.

Caller: Pennisula HR

Nice people offering HR Support

Message said this is Sandra please call me back. It was Peninsula something... so I hung up!

I couldn’t even hear what he left on his voicemail, sounds like he did that intentionally, so people would call him back
