Jabong.com — bank details ifsc code error

I received my order from jabong but the item that i bought is not as i expected and a little big so i opted to return the item since there's no smaller size. When i provide my bank details for the return payment there's an error in the ifsc code which i have provided. The ifsc code is correct and i have check it so many times but still it wouldn't accept the code. I gave the same ifsc code before but it does not give any error. I'm really disappointed with jabong. Please look into this matter. I want to return the item and get a refund.
