HAHAHAH @ Manzcar, you have a very very good point!!!!
Yes, we have a do not call register too!
Last time mum got a call at home and i taught her to ask the lady, wat company she's from (they're very happy to give you the answer) then say "i'm registered on the do not call register", and they go all apologetic and thank you for your time LOL!
But the register doesnt work for Business, only home phones, so at work we still get these annoying telesales...
and... somehow.. i do get sales call on my mobiles too! (not very often though) But i can put my mobile number on donotcall as well.. so i guess its all good...
@bel - we got conned and we're locked in a 24 months contract
