I have receive the email from a consulting firm that the invoice issue by me has not been showing in 2A of their portal. Hence , they claim gst amount + 18% of gst amount from me with the warning that in case of not paying the amount , they will be entitle to deduct it automatically from next payment.
I have filed the 3B Correctly but the problem is in GSTR 1. In the GSTR 1 of said period, the invoice has been field with wrong (GST number of someone else) GSTR 1 . Now, I cant amend it since it is a invoice for the year 2017-18. What is the provision regarding this problem and any suggestion ?
