Bought my twins an iPhone 5s for their birthday they needed a new SIM cards my partner took them out to buy all this came home and said they charged him £5 for the sim and had to buy £10 credit twice! So £30 wasted as they already have sims with credit on we just needed the nano sims. We have been back to carphone warehouse twice two different stores the first one confirmed we did not need this as we already had and said we just need to go Vodafone who would give us the sims free he advised us to go back to the store we purchased the sims from and ask for a manger who would be able to refund us. So third visit no manager we will have to come back tomorrow but they also said they don't refund! So my partner was conned in to buying two sims and credit that we don't need and can't seem to get our money back for. Becarefull as they lie and and confuse you just to get you to buy and then lie that they cannot refund you.
