Why was my phone not sent to istore to be repaired

I handed my iphone in Mid december for repairs as the screen went blank.<br> I was also told that the system needed to have a password sorted out and they would book it in, once this was sorted. This took a couple of days.<br> I asked them to confirm when handing the phone in that it was under Warranty. i was told yes. We went away on Holiday and on my return early January I was called to tell me to take \find my iphone off my computer as they could not work on it while this was active. I struggled to remove it with the first time them telling me i was not successful. This took a further few weeks delay.<br> Once i was successful in deleting this, my phone was sentback but once again a hold up with the password in booking the phone in. To cut a long story short after 3 months i am now told phone not under warranty and i need to pay R 3517.00 to have phone now repaired. WHY WAS I TOLD WHEN HANDING IT IN IT WAS UNDER WARRANTY., Bought phone 18/11/2014 and phone broke early dec 2015? When collecting my phone after all this, the assistant brought me new phone in box that had a stamp \"one year warranty\" !!! <br> Y DID MY IPONE NOT GET SENT TO AN ISTORE AS IT IS AN IPHONE??"
