I have been plagued by phone calls from people selling things. Double glazing,insurance, free holidays, evrything you can think of. I am fed up of this, sometimes when you answer the telephone there is a dely, and you know that it will be someone trying to sell you something, so i usually put the phone down right away.
However i found out that there is a telephone number you can ring to block the incoming calls, it is called PPS and the phone number is 0845 07 007 07. I have used this number and I am not getting any calls at the moment.

Shame you carnt do that with the post!!
