DENIAL OF ITC DUE TO SUPPLIERS REGISTRATION HAS BEEN CANCELLED UNDER SECTION 29(2)(e) - Goods and Services Tax - GST

DEAR EXPERT, MY QUERY IS UNDER. I am manufacturing firm. I am purchasing raw material from different suppliers. Sometimes we are purchasing from agents. So we dont know the supplier personally. We have received 3 different DRC-01 for the F.Y. 2018-19 stating that suppliers registration cancelled suo moto. hence ITC need to reverse. initially they have issued summon to us and we have supplied documents as they required. but off the record, they told us that when ever any suppliers GST number cancelled we demand ITC from the receipient too. in one notice they even not issued DRC-01A . We have documents like invoice, E-way bill, payment proof. What can be done in this case.
