'We are freezing prices for a year' can be roughly translated as 'in a year we will be doubling our prices'
As you say, how stupid do they think we are?
I think if Tesco froze price of every product for a year, you'd be happy 
Maybe I'm just too cynical these days but the way they make the advert sound, as if they're doing you the biggest favour in the world by not putting prices up for a year, when you know that after that, you're going to get clobbered with a big rise after that, and you know that they make huge profits every year regardless, gets my goat.
Yes, there are services that we could use instead of sky, but there are some good channels on there that you don't find anywhere else, just have having to pay for it 
So your getting the channels you want at the same price as last year, when everything else, Petrol, Food, Clothes are all going up in price?
Sky customers get on the move access, get your TV via phone (android coming soon) PC/Mac & iPad at no extra cost. You get Anytime+ a router which plugs into Sky's vast online stock of movies. Again, new service no extra cost, Sky Atlantic its basically a whole new channel bought of HBO. Again that cost nothing extra....
What do you want? The world on a stick?
Can't please some people

Damned if they do, Damned if they don't
