In the month of Sept 2017 I have raised an invoice to my vendor for services provided. But that invoice is not approved by the vendor that means I have not been paid. Whereas in GSTR 3B filing for September, I have shown this invoice data and paid GST for it. 

Now what has to be done by me to get back the GST Paid by me, which is around INR 6000.
