Jabong.com — customer state is required to process the return

I ordered two pair of shoes.. The delivery was on time.. Both shoes are good looking.. But one pair didn't fitted good.. So i thought to return that pair.. When i tried to return tge pair... After filling all the details like name address for pickup.. Refund process, bank account details.. All these were duly filled by me.. But after confirming the return.. An error was shown that read"customer state is required to process the return"
I would really appreciate if you please help me solving out this issue as fast as possible..
