[Resolved]  Fastrack — Servicing Centre not fixing the problem

I bought a Titan Fastrack Watch. It has a warantee period of 2 years. The wrist watch stopped performing before one year from purchase. I gave the watch for repairing at the company's servicing centre. They fix it. But the same problem occured again. They again fix it. For the third time, it has stopped working again. Do I have to go to the servicing centre again and again? What are the things that can be done. I don't want to carry on with this headahce of going there again and again. Please help.
