Anyone got sky through vodafone? in my experience it's great having the discount and works smoothly... until you need an install

Without going into tedious detailed accounts of all the phone calls,
I have had to tell vodafone my address and correct contact phone numbers 3 times, and sky directly, 2 times. 
Vodafone seem unable to efficiently or even effectively communicate to sky.
Sky on their part won't talk to me as a customer, although sometimes they do but lie (fail to act on anything after telling me they will). 
From hearing a vodafone csr moan about them too, sky seem to be obstructive and slow to act on anything vodafone want them to do for their customers.

I originally asked vodafone for the move 2 weeks before moving. 
I was annoyed enough with chorus taking 5 days to install. (Not doing installations on weekends and public holidays, the days people usually move house, is just rubbish). 
But that aside, I was ringing daily about sky. After various plausible explanations but a whole lot of stress and time on my behalf, I decided to hand off to my wife because it was stressing me out every day. 
Her approach of demanding a result and not listening to excuses probably worked better. She is certainly claiming it! Though I suspect the process might have just finally wound its way through the maze and was in the home stretch when she rang.
We finally got it installed yesterday, 13 days after we moved.
I'm now looking forward to the bill when it comes (not)! I did already get a $50 credit on day 3 when Vodafone screwed up my address, but I that seems like a standard credit (4th internet move/change in 3 yrs, and not just vodafone) when something takes a bit long. 

So thats that.
But on another note, what's the phone jack that the installer strung off our demarc and put by my TV? 
I would love to use it for my router, I never have or will order pay per view stuff from sky.
I tested it, but it must be some other 'sky' line? It didn't give me adsl.
