Godrej/ Washing Machine — replace of wash motor under warranty period based on purchase bill

I have purchased a washing machine godrej gws 6502 ppc semi automatic top loading on 01 november 2015. Recently it is noticed that wash wheel is not functioning. After checking of technician of godrej coy it was found that wash machine is required to replace. Technician told that wash motor which is under warranty and can replace only after produce of warranty card. But unfortunately the warranty card has been misplaced by me. I have only original bill which was got during purchase from chanda electronics, bareilly, up. Now i am requesting to arrange replace the wash motor of ibid washing machine based on original bill.
