Exide Industries — replacement of two wheeler battery under warranty period

I have bought two wheller exide battery, now it is down and not working.Previously just before 4 months ago same thing happened also, and I sent it to the service centre, but they sent me the same battery afer cheking and charging it saying that the battery is being found ok without replacing it by new battery. The process also took long time nearby 1 month.But now the same thing happened again and the battery is not working. So again I have sent it to the service centre via the shopkeeper from whom I purchased it. So now my request is that this time I should get a new battery in place of sending the same battery again and without delaying longer.
