Jon - I do the same myself
Sky Magazine. If you subscribe to Sky you get a magazine through the post every month. I never read it and it just goes to the recycling which is really annoying. So I had a look through it to see how I could cancel it. On page 10 it says - I quote '£2.20 of your package price is paid by you to BSkyB Publications for this magazine'
So, I phoned up and said I wanted to cancel the subscription to the magazine and they said fine - no problem. When I asked if that would reduce my monthly bill by £2.20 they said no because the magazine was free!
When I pointed out that it says in their magazine that I am paying £2.20 for it, they said that the magazine is included in the monthly subscription amount and they can't take it off. Computer says no!!
Well, excuse the f*ck out of me, but if they are telling me that I am paying for their advertising sent to me and then when I decide I no longer want it they think it's ok to charge me for it anyway!
I am awaiting a reply from a senior manager. Could be fun!
