I've used dial a phone twice and on both occasions this has happened. I ordered a phone on C902 on Vodafone, I got an email saying the was a problem and to contact them, So I did, I got told "You have not been accepted on Vodafone but we can do that on o2" which was fine but it makes me wonder if there is an alterior motive, Same happened last year when I wanted a K810i on 3, I got accepted on Orange instead
