Caller: A British male voice

Unknown

I did not answer and they did not leave a message. I don’t answer any calls unless it is in my contact list. If legitimate, they will leave a message.

I called back but no response

Unsolicited call. No message left. Suspect scam. Blocked

I didn't answer cos I didn't recognize the number and wasn't expecting a call

i missed the call but decided to call back and a robotic voice said something about a charity

Missed a call from this number but he never left a message, I reckon it's a scam.

Caller: I don’t know

Nothing

No voicemail, no details pnline - likely spam/scam

Didn't leave a message
