India calling....

I am at my wits end... for the last 3 weeks or so I've had 3 (sometimes 4) calls from some company from India... and they ask for me by name and say they're doing a survey for electricty blah blah blah... I was polite at first and asked them not to call me, 'I am not interested', 'please take my number off the computer system', 'I am registered with TPS' (so they can be fined for calling me like they are)... NOTHING WORKS!!!!!!!!

My politeness has now left the building!

Hubby says when I hear the long delay (and so can assume it's them - apologies of it's any of my family overseas phoning! )... I should set off the little mobile squeeling alarm I carry with me... which I cannot do when the kids are here of course - would scare them half to death! Plus it's not pleasant for me either to have to always do this. It's an awful noise.

Today's three calls got no response at all, I picked the phone up and said nothing... they put the phone down on me. I just cannot carry on like this though... it happens at any time... and is often when I've just got the kids down to sleep or am in the middle of a pooey nappy or something.

We have two phones and neither have numbers that come up... and they're phone fax systems so would be very expensive to replace.

What can I do to get them to stop harrassing me???

HEEEELP!!!!
