Well I've been 'missing' for a couple of weeks as no broadband due to an error on my side. I mistakenly asked O2 for my MAC then joined BT for an extremely short time fo 4/5 days (god knows why as I hate them) immediately after ordering I knew it felt wrong so phoned them to cancel my order. I'd also transferred my landline back to them from O2 too so this was inclusive of cancellation.
After all the years I've been on BB (and dial up) I thought I had more sense! I've had to wait until the supposed BT activation date expired to let Sky transfer me via their switch side and can say now Sky have been marvellous about the whole thing! Sky went over and above what their had to do regarding my stupid error and were constantly in communication during the whole process, which included trying very hard to tranfer me when BT mistakenly kept the landline.
It's been one **bleep** up after another,plus two weeks without BB only using the data on my mob. I know full well I should've realised I'd be without BB but I didn't until the O2 guy in accounts told me what to expect.
I can't sing Sky's praises enough at this present time-long may it continue-and to thank O2 for their valuable help and services over the many years too.
Forgot to add I also got a smashing deal with Sky of free unlimited BB for a yr, plus 3 lots of various deductions off my husbands sky package 
Bt also gave me free landline until the change over due to it being their error of not cancelling the line-I'd paid 1 yr up front which was refunded.
Sorry for the saga
