Refund against tds

Hi,

For assessment year 2012-13 (FY 2011-12), I worked as an intern for 3 months (approx.) and recieved salary and TDS to the tune of 10% was deducted by the company (details in form 26AS). For this period I recieved no other income. TDS decuted is Rs.3711.

Kindly suggest how to receive this back as I do not fall in the minimum category for tax.
