Consumer Redressal

I ordered a bag from yebhi.com in January this year. The product which was delivered to me was defected and I promptly returned it. Although I paid in cash, they refunded my amount via an online wallet on their site which could be used to buy products or refunded to my bank account at any time. I tried to refund the amount to my bank account once, but the transaction failed due to some unknown error on their part. In July,when I called up the customer care and told them that I want my money transferred to my bank account, I was told that the refunding of money to bank account is only valid for 30 days after the return of a product now due to the new policy of the company. Firstly, I was never informed about this policy change by the site. And, secondly they are holding my money against my wishes by some \'policy\' that they have come up with overnight. Although, the amount is not huge but its a matter of ethics for me and I would like to make this fraudulent company pay for this.
