Bill Not Uploaded by Supplier In Gstr-2A

I have Received A Service From My Supplier & Received A Gst Invoice For Which I Availed the Itc in October-2018 Return
Now A few days Back I have Received A Notice that i have Availed the Excess Itc(Bill Not Uploaded By Supplier).
I have the Gst Invoice,I have Paid Such Amount through Cheque (within 180days) & Yesterday It Came into My Notice That the Supplier GST Number Was Cancelled Before Providing Me The Service i.e. in April-18
Whether I'll be Liable to Pay Such Amount Or Supplier will Be Liable?
