Itr refund status

Hi,

Have filled my ITR on July 31  and acknowledged the same by 01 Aug itself. Usually the refund happened in a couple of month where as this time so far no action. Upon checking the status the website is saying that  : 

1. Your assessing officer has not sent this refund to Refund Banker.
2. If this refund has been sent by your Assessing Officer within the last week, you may wait for a week and again check status.

I have not received any reply to grievance sent to AO { email id received as per record } and none of my calls were answered

Can anybody guide me here 

Regards,

Kurian
