Delay -Refund

My ITR was processed on 11 Aug and shows Refund awaited and in NSDL website, it shows no records available. Generally they used to update the NSDL website within 4-5 days but this time i guess many are facing the delay in refunds. 

People who have received refunds, how much time it took for this AY after receiving the Intimation ?

I had similar experience, received after 15days
