One of those robocalls where they have a couple of prerecorded messages about an "accident that wasn't your fault", Then if they think you're gullible enough, Pass it on to a marketer.
Called asking about an accident I was involved in that wasnt my fault (and that has never happened). I dont know whether it was a computer or automated speech but it seemed to speak oddly and didnt react to my repeated asking "who are you, What company are you from"... Then hung up.
Company behind this nuber is calling TPS registered numbers so its a scammer or fraudster
Said they were from Warmer Homes Scotland but that is a scheme supported by the Scottish Govt. Think they got my details from a comparison site or my new energy supplier but wouldn't confirm.
