Amazon.in — No Refund Given for faulty product

Address:	New Delhi, Delhi, 110086
Website:	www.amazon.in

I had ordered a product from amazon india but I found the product not appropriate upto mark therefore I requested a refund . After 15 days they issued a cheque with wrong name on it and Before the issuing of the cheque I had been constanty calling them for a name change but they had sent the cheque on the wrong name. Then I asked them for a reissue of cheque they had sent an authorization letter . I had filled it but the cheques hasn't arrived till yet it has been 2 months since the filling of authotization letter and their policy says refund is issued in 10-15 days. I want to take a strict action against them for not returning my money till yet.
