Amazon India — Hush puppies product damaged in 30 days and amazon not accepting return saying 30 days is up

Address:	560103
Website:	Amazon India

I have bought Hush Puppies sandals from Amazon India site. The product got damaged with holes and soles coming off after normal use. I have used the product only few times in the first weeks thinking the product would stay upto its mark and since i trussted the brand Hush puppies. After 30 days only i have strarted normal use and found the product is completely damaged one.
I have raised complaint with amazon. They told me to contact Hush pupies care who in turn asked me to contact Bata India. The bata accepted that the Product is damaged and they agreed for refund of money. But now the amazon have turned plate saying 30 days is up and cant do anything.
Where is the logic in that and how can a normal guy predict the product is going to get damaged. Its pure cheap service from Amazon.
