Completely new iphone logged into someone elses apple id

Question

So recently I got the new iphone 5s (completely sealed in plastic) as a late Christmas present but when I opened it up and tried backing up from my iCloud it asked for the password for someone elses account (I'm not sure anymore but i think it was amandamcvittie@bt???.com??). Anyway, once that came up I decided to leave it there for then and headed over to Apple's Bluewater branch, where it had been purchased, to ask what was wrong. When I got there and approached a worker I was told that there was nothing to worry about and that I should just skip the step and delete the additional account when I got into the system. Another problem was that when the iCloud had been backed up there was an error or something and it went back to the start up screen again (something I was told was unusual but nothing to worry about and which was also ignored) so I had to go through the first few steps again and yet again ignore the amandamcvittie question. Regardless, when we (we being the worker and I) finally reached the main app page of the phone we went to settings and scrolled down to the iTunes and App Store option only to find that the Apple ID was clearly mine. Having seen that we proceeded to check the iCloud option and yet again the account was clearly mine. Unable to find anything that noted the existence of any other account on my phone I was told that there was nothing to worry about and that it probably wasn't anything major. Still slightly unconvinced I went to the App Store to ascertain whether I could download apps without being asked the password for amanda's account. Having downloaded the featured 12 Days of Gifts app without any problem I decided to trust the workers and headed home.
After arriving home and connecting to my internet I pressed one of my apps to begin the downloading process of all my old data (music and apps) and was asked for my password but once I had given my password another pop up asking for amanda's password appeared. Without giving it much thought I simply pressed cancel and the downloading began. Realising what I had done I regretted not taking a screenshot since I was unaware when proof that the amanda account was still stuck in my iphone would appear again but I was not to worry as when I checked my music I saw that there was an unfamiliar album there called 'The Lumineers'. Once everything else had been downloaded this album stayed grey so I pressed it to see what would happen and if the pop up requesting amanda's account password would appear but instead of that it just began flashing and trying to download or something (it looked pretty creepy). I just checked and it is still flashing. This is a picture of the album when I click on it because I did not have the chance to screenshot anything else when it came up.
I could always upload a short clip of the album cover flashing but I can't be bothered right now
I went to the Bluewater branch again today and was told that I could exchange my phone for another one but I didn't have the original receipt with me so I have to go again.
But more importantly I just want to know why there was someone elses apple id on the phone and why there's an album there? I don't mean to jump to conclusions but doesn't this mean that I paid for a new iphone only to find that it had already been used by someone else before? Has anyone else ever had this happen before?

Hi
Just got my wife a new iphone 5s phone from Three shop and exactly the same has happened. The Apple ID was [email protected] and every time it goes to download an app it asks for their password and then my wife's password. So weird. Taking phone back to the shop tomorrow for a replacement !
