UMESH (ACCOUNT EXECUTIVE) (57 Points)

We are a manufacturing company registered under GST On filing of GSTR-1 for the month of October-17 we have wrongly filed 1 GSTIN to Another party's GSTIN for name confusion like (LGB Forging Ltd to LGB Foundry Ltd 😇). The party asked us that the bill was not shown in GSTR-2A. Now my question is, Can we amend the GSTIN in August 19
