Myntra.com — refund for the product which was cancelled

I have placed an order on 14sept and have cancelled it on the same day because I ordered the wrong size. The amount was deducted from my bank account that day itself but I still have'nt received my refund. At other days when I give for refund I receive my money on time but for this cancellation it's taking a lot of time. So I'm worried whether it will be credited to my account or not.
