[Resolved]  Titan Fastrack Wrist Watch — exchange or allow to buy new wrist watch in bill amount

dear sir,
I just purchased new titan fastrack wrist watch with 2 years warantee, model no. 3009nl01/c143b, bill no. 001791, bill amount Rs. 2900 on dtd.[protected] from retailar named mangabhai & sons, navsari, gujarat.
In few days the top key of watch was loose out from the watch. Retailar charged me Rs.150 for reset the same. Now again same problem occurs.
So that i am requesting to exchange the same or allow me to buy new watch in the same price.
Hope for your kind & fine support.
Regards with thanks.
