when i speak to them they're always pretty honest with me.
my tariff is £30 (for reasons too complicated to explain i get the data free for life) they tell me £15 is for the contract and £15 is for the phone. and i can break it down however i wish.
but they just tell me the cost of the phone i want, then i can work out the deal for myself.
last time the deal worked out better than i could get else where so, in that case there is no point in arguing.
outbound may offer something better, but then it's a funny game, but they wont offer you something that is better than you can get else where. if you're going to go that route then ask for you PAC in the last month and see what happens.
you need to do your homework see what deals best suits you and put it to them.
