I also received the intimation on 27/7/22 but got the refund of Rs.4000+ credited on 26/8/22. But my friend got the intimation on 6/8/22 and refund credited on 21/8/22 in 15 days, that too a sum of Rs.56000. The System selects in a particular sequence probably. So be patient and you can wait for another 10 days...
In the meantime, please ensure that your Bank a/c is validated and nominated for refund.
You should check your emails in SPAM Folder as sometimes any clarification from ITO/CPC will go there.
Again, open "Pending Action" menu in IT Portal and check in 'Work list" and ensure "There is no item in worklist for action"/information".
Lastly, please check your Bank account daily and check if the credit has come. This may sound foolish but sometimes the email and sms might have been missed but bank a/c would have been credited. (This happened to me once).
Finally Dont forget to confirm the receipt of credit in this CAclub forum for the benefit and knowledge of other members.
