My accountant has wrongly paid the GSTR 3B return amount for Sep 2017 under IGST head instead of CGST & SGST head. The same has been credited to my electronic cash ledger under IGST. We tried contacting the GST helpline however haven't received any positive feedback yet. Can somebody help us out to get the amount re-credited under the correct sub heads (SGST & CGST). Thank you in advance.
