Customs order Issued to repay Drawback with interest

Dear All,

we are doing Export of Garments. for the same we will receive DBK Amount.

and recently we have received the notice of Order passed by the customs office to Repay the DBK Amount against a export for non realisation of eBRC.

actually The eBRC is realised against the same shipment.

kindly suggest me how to close this issue.

do I need to write a letter to Customs or how can we resolve this issue.
