Foreign Inward remittance certificate (FIRC) is not received in USD dollar


I am selling my product on in USA , but payment received in INR.
Basically, if we can sales the product in USA and we received payment in USD dollar and after that we need FIRC from the BANK.

Selling though Amazon marketplace, we had received payment from in INR through HSBC Bank, HSBC bank even do not issue and send the FIRC for the said payment.
We need FIRC to get the BRC for the said shipment.

Please advise what to do…
