We've had something of an epidemic of this kind of rubbish over a period of a couple of weeks - two or three calls every day using both my home and mobile phone numbers. I really went off the planet at the last caller (my wife was shocked, and I believe that I surprised myself too).
Nothing now for the past three days - have they all died? Have they really given up on me? Did my tirade work? One can only hope ...
Edited to add: NO they haven't, mid afternoon. phone rings "private number" in the display, there is silence of about three seconds, a brief bust of noise which could only come from a call centre, then the voice ...."Hullo?" Phone is replaced on hook. I am tempted to go out in the back garden and shout obscenities ... Some measure of self control is retrieved, and I go back to what I was doing ...
Except that I can't remember what it was that I was doing .....
