Does this in any way break any rules & regs ?

Did it ever occur to you that the folks calling you are trying to earn an honest living? Why is it that you are so weak kneed that you find it so earth shatteringly difficult to politely say no thank you and put the phone down.It appears that you are in the UK , I know for a fact that all you have to do is call your telephone provider such as BT and register with them and they will stop all unsolicited calls. Grow up and stop being so nasty.
