Apple India — camera auto focus problem

Address: Rajkot, Gujarat, 360005

When I click any pic with focus it become blur. I'm using iPhone 5s. it has auto focus function. So whenever it auto focus or I focus it manually photo get blurred. Like my phone's eyes are week. I visit apple store on 26th July, and they returned me my phone on 3rd aug. But problem was still not solved. I visit again on 5th aug and they returned me on 21st aug. But still problem is not solved. In that period they said that they send it to Benglore. But still they can't solve my problem. It almost like a month. But their response is too poor. I didn't buy iPhone to keep it in service centre. it is the worst service I have ever seen. I can bet that any class company provide you better service. They have started E -recycle, but tell them to first repair iPhone which are in still in warranty. This Apple service centre is in Rajkot, Gujarat named B2x. I attaching some pics of blurred pics.
