[Resolved]  Titan Fastrack — Repairing

I have bought a Titan fast Track watch model No. 116/SM02 dated 05/07/08 from Shopper's Stop, Shipra mall, 9 vaibhab Khand, Indira Puram, GZB-201012. But after some days it stopped and I had gone for reparing on 13/09/2008. After 40 days they have give the same watch back without any reparing (right now it is stopped). What should do I do?
