One of my supplier supplied a material in June, 2021 for which total payment was made within 3 days. The supplier duly uploaded the invoice in June, 21 GSTR-1 & ITC was duly availed in our June GSTR-2A. Only one invoice transaction took place with him. In july, 2021 when we were matching our GSTR-2A, we were shocked that he has reversed ITC vide Credit Note although no Credit Note was given to us & no eway bill is there against that credit Note. He has not even filed GSTR-3B for month of June, 2021. This seems to be a fraud on us. Now what is the remedy available to us. Whether any criminal complaint can be filed against him so as to set an example for others. Kindly advise.
