When I picked up the call, they immediately disconnected, which raises my suspicions about it being a scam.

I haven't the foggiest who this could be. They disconnected the moment I picked up. I'm definitely adding it to my block list.

I didn’t recognise the number, so I opted not to pick up. Clearly, it mustn’t have been anything urgent since they didn’t bother to leave a voicemail.

Yet another unidentified caller.
