I called back. Recieved abuse and swearing from a woman and a man. Also said they would "come and get me" and something about a pistol down my throat
There was also another asian sounding man in the background. Have reported numbers to the police.

Missed call, called back and was abused. I was heard "you'll get a pistol down ya throat" and a woman screaming about missed calls. Sounded like several people on the line. Very annoying.
