I do not understand how you did this. You have to declare the goods for export with your IE Code before the Customs. Then Shipping Bill is obtained details of which flow to your bank through RBI via EDPMS mechanism. Then you can give all relevant documents including Invoice, Shipping Bill, Transport document etc to your bank for collection who will forward documents to the banker of overseas importer.
It's likely that Customs and RBI also may initiate action in the matter as you have violated the basic rules governing export trade.
Better you contact a CA who is handling the export related issues to represent you and to guide you. Posting queries in this forum will not help you as the matter is not for a mere clarification.
