Thanks for the information guys. I'm now going to have a little rant
People have mentioned that when my 50% friends and family deal runs out in 12 months then my package might not be attractive. I agree however right now I feel more valued by SKY than I did with Virgin. I'd been with Telewest / Virgin for about 10 years. Since Virgin launched I've pretty much had their VIP package plus 2 mobile phones. I'm certain Virgin would have classed me as a high end or high spending customer. When I received my price increase letter in December I was actually only 2 months into a new 12 month deal due to changes I made to my package at the end of October. I called Virgin to tell them I wasn't happy and that I planned to change provider. I then called back 48 hours later to cancel explaining the deal I had managed to get via SKY. Virgin had the oppertunity to show how much they valued my loyalty and custom by matching the offer from SKY but they didn't. Virgin would rather lose me as a customer than match a rivals price. Both my mobile deals are up next month too. As I won't get a customer dicount anymore their deals aren't as impressive. The wife and I will be switching mobile provider. Virgin where getting about £1960 from me annually, from next month they will be getting zero.
