Invoices transmitted to icegate but refund not received

The refund application was filed on the GST portal last year itself. The Track status of invoice data to be shared with ICEGATE says that the invoices have been transmitted to Icegate. There is no errors mentioned there. But we still haven't received the refund. When I check the ARN status, the assigned to says NA.

Is there anything I can do to expedite the issue of refund? Thank you.

in case of export of services with IGST payment we have to file RFD-01 along with R1 & 3B, Otherwise in case of Export of Goods with payment of IGST GSTR 1 Table 6 and 3B is enough to get GST refund
