Said it was "Sam from Energy..(mumble)...." Have a feeling it may be one of those ones where they try to get you to say "YES", because I said initially "it is" then they asked question a different way and I said "YES" ... that's when the line went silent. So I'll be keeping an eye on bills, bank accounts etc etc just in case

Could this be a scam

Calls my landline (which is private) a few times a day but never leaves a message. I'm going to block this number as it's really annoying.

They called a few times over the last few weeks. Showed up as suspected spam on my phone so haven't answered yet. Rang the number back a few hours later. It is nor connected. Have blocked it now.

Haven’t answered, several calls, no message left

Three calls, no messages left

Constantly calls. Answer then hang up straight away
