02038777098 - unusual for scams, 3 mins after unanswered call I got a message, listened to it, just voices in background. Would have been a charge to return the call, and pretty sure this was a scam, so deleted the message. Is this a ploy to make us think it is a genuine call, and tempt us to return the call?

Spam call who hung up when I challeged them on pick up. When I called the number (0203807798) back it didn't connect but went dead almost immediately.
