Anybody know anything about Discreet Numbers? My mobile started ringing but cut off almost immediately after playing two notes of the ringtone. It showed 'missed call',didn't recognise the number,dialed it and got a message saying "Welcome to Discreet Numbers. This number is not in service. For more information visit our website www.discreetnumbers.co.uk". I hung up and looked up the website but can't find it. Is this some sort of scam?
