Was wanting sky+ plus for home but was not willing to pay the £99 for the box and £60 for installation so.... after being advised on what to say...
"Welcome to Sky, how can I help you?"
"I would like to cancel my Sky subscription"
"OK. I will have to go through some details. Why are you looking to cancel?"
"Because I have taken up a few new hobbies and am not in to watch the programs I would like to watch"
"Would Sky+ be beneficial to you?"
"Yes, but I have been a customer for nearly 6 years so do not feel I should pay for it, besides, I cannot really afford it....."
"Would you be willing to stay with sky if we did the Sky+ box for £49 with free installation?"
"Eh, yes. "
So.... worth a shot if you are wanting Sky+. I think I could have manged to get it for free if I had tried, but was happy paying £49. My box is now as old as my sky system and they do not last forever, and I get a new satellite dish, so all is good IMO.
