NO,NO,NO...

Why won't people take NO for an answer?
On Friday last week I answered the door to a young chap who was trying to sell me Sky TV, and despite me repeatedly telling him that I wasn't interested and was quite happy with Cable and Freeview he just wouldn't give up.
He had an answer for everything, including that they would cover the cost of having a BT phone line installed- Yeh Right!!!
He eventually got fed up and went on his way.
Monday lunchtime the doorbell rang and there was a young woman who started off with exactly the same spiel as the chap on Friday. Twice I said I wasn't interested, and eventually I said to her "Why can't you just accept that I'm not interested and go away" then I shut the door.
Monday evening at 8pm the doorbell rang and there was another young woman with exactly the same opening line. I told her she was the third person who had called, and she said that obviously my name hadn't been crossed of the list.
Now one caller I can take, two is a bit much but three is as far as I'm concerned harrassment. I asked for the name of the company and phone number, which she gave me straight off, but when I tried to call the number this morning the number came back as not recognised. So it seems to me that it must be a pretty dodgy outfit that finds it necessary to instruct its workers to give out false information, as well as being against the law.
Now I can register with the Telephone Preference Service so as not to get unwanted marketing calls, with the Mail Preference Service to not get unsolicited mail. Its about time I could get my name on a list that says I don't want people knocking on my door trying to sell me things.
