They say they are from gallop and want to do a survey on living in England. Block them otherwise they will just keep ringing

Call from a call center, no introduction expecting me to say hello to them end the call but instead after about 15 seconds they said hello. No clue who they are, probably checking to see if people's numbers are active or in use.
