Nokia E5 — Damage of my phone

Address:

Surat, Gujarat

Hello, i brought new phone Nokia E5. For updating my software, i went to nokia care. I got my phone within an hour. When i reached home i i came to know that my phone was damaged from left side. But because of lack of time, i was not able to go back to the customer care. I went there after a day or two. But now they refused to accept that they damaged my phone. And it will cost me Rs. 700 for changing the body part. Now what to do? My phone is also in guarentee..!!
