Don't call us, we'll call you.

Since being off work during the day I've found that my home telephone number is subject to an increasing amount of calls from nuisance cold calling companies trying to sell me things (no specifics, I rarely get past the opening sentence).  'Hello?... (10 second wait, or the best one, a ring like I'm calling them)... Hello, I'm Rajesh calling from *CLICK*.
I know these guys are out to make bread, most of the time I do take a moment to explain to them that I'm not interested and that I'm ex-directory, I'm not supposed to be receiving marketing phonecalls as I'm on a register for it, and 'HOW DID YOU GET MY NUMBER???' to which they reply with something along the lines of 'oh but we're trying to give you a better offer than your current energy supplier!' *CLICK*...
I do however draw the line when they call and say 'Can we speak to a Mr or Mrs Mudd?'.  I used to tell them that neither Mr or Mrs Mudd were available as they didn't live here, until they cottoned on that I was the woman of the house and I was not married.  Now 'Can we speak to a Mr or Mrs Mudd?' is met with a hearty *CLICK* of my phone hanging up.
I am an avid user of Skype nowadays and was appalled to see that even online telephone use was not free of these nuisance callers.  I was shocked to receive a call from a robot this afternoon attempting to sell me computer protection (?) it appears that Pop Ups are not the only annoying marketing strategies being employed throughout the internet any more... Fortunately I was able to hang up, censor future calls and even block the computer from calling me and selling me things, surely this would be a brilliant addition to BT's phoneline protection from these annoying people?  
If I indeed wanted to save myself money on my energy bills, wanted a grant for heating insulation, was interested in signing up for some scheme or other I'll get in touch with you.  I'm happy to keep 'paying more' with my current energy supplier because they don't call me up and annoyingly hassle me all the time thankyou very much.  Next time you call, I will be employing this technique for comedy value for myself.  Annoy me, I'll annoy you more.  *CLICK*
