There is rumour that if you call sky to cancel then they will tell you that they can make your monthly fee lower.
I should mention that my sky bill was £20 a month. It is now £22 a month. Overall, the increase has added over a whole additional month of charges to my annual bill.
If the service I got was uninterrupted and smooth then I'd be OK with the increase of charge but considering i'm not happy with the service as it is i'm rather miffed they've added an additional month to my bill.
