IF Supplier not deposited GST PAYMENT ?

HI EVERYONE

I HAVE SOME QUESTION REGARDING INPUT GST CLAIM

I HAVE PURCHASED A MACHINERY AND CLAIMED INPUT GST  OF 9 LAKHS ON IT (AUGUST 2020)

NOW AFTER FEW MONTHS I CAME TO KNOW THAT MY SUPPLIER HAS NOT SUBMITTED AND PAID GST TO GOVERNMENT (ALSO NOT REFLECTING IN MY 2A).

NOW WHERE I CAN FILE A COMPLAIN AGAINST HIM LEGALLY

PLEASE HELP
