Official Apple reseller says "iPhone 5s's camera is much worse than the other"

Question

Hi Apple support and fans,
I am writing to ask you and maybe get Apple's attention to what happened to me. I bought an iPhone 5s 8 days ago. I bought it from official Apple reseller in Warsaw, the capital city of Poland. And then my adventures began.
First, the plug is British, not Polish, because as the reseller said "we have some iPhone not from official distribution, but it will work". Because I needed to buy an iPhone5s fast, I accepted that. However, the question is still there - is it legal to sell British iPhones "from unofficial distribution channel" in Poland?
Second, and more important, my iPhone 5s makes horrible blurred pictures. I mean they are really blurred... I read all the posts on this forum and I tried everything. Finally I decided to visit the reseller and here is what their representative said: "These pictures are totally fine. They are blurred, as this is not a professional camera". Wow! What a discovery. I know that this is not a professional camera, but I know how photos from an iPhone (4 and 4s) might look like. So I replied that something is strange and I wanted to give my iPhone back to check it (under warranty). The representative replied: "We will not take it, and I'm telling you the pictures are all fine. The camera in iPhone 5s is much worse than it was in iPhone 4s and hence the blurred photos. Just live with that". 
And now my questions:
1. Is it true that the pictures must be blurred in iPhone 5s, just because it works so? I can't bvelieve it.
2. Isn't the fact that they sell iPhones from "unofficial channels" the reason why they don't want to take the iPhone under warranty?
If anyone from Apple wants to take a closer look at this issue and maybe discover some "strange" actions from Polish official Apple reseller, I'm open to provide you much more details on the purchase, the store location, etc.
Looking forward to hearing from you,
Kuba

iPhones are ONLY sold by Carriers and Apple an Apple reseller is unlikely to be authorised for iPhones and certainly would not sell an iphone with a foreign plug
You have clearly purchased a grey import a genuine Polish sourced iPhone sold by a legitimate iPhone reseller would have the correct plug for the Country
Big issue you have is warranty you need to take to an Apple authorised repairer

luckily as long as iPhone came from UK you do have warranty ,EU is one "country" for Apple warranty purposes
