Myntra.com — refund failed

I ordered slippers from myntra and didn't like so decided to return them, return number is [protected], i waited for like 5 days although myntra's policy says that it takes only 1 to 3 days to refund the amount in saving account, so i did recheck everything and found that
By mistake i entered wrong account number, that means account number is not valid so they can't process refund on that a/c number, since in this case i can't contact bank and i don't know how to connect with myntra for this case so please if there's any way to reapply the return request with new account details.
