Clarification regarding vat liability

I am a registered vat dealer in Karnataka. Our supplier has raised E-sugam on our TIN number, hasn't supplied the stock and he has forgotten to cancel the E-sugam within 48 hours.

Now the problem is sales tax department has downloaded the details of E-sugam raised on our number and questioning the details of the same for which the supplier has forgotten to cancel.

The supplier has also admitted his mistake and given in his letterhead stating that he has forgotten to cancel the E-sugam and also written that he has not supplied the stock to us.

But the sales tax officer is telling that he will issue a notice demanding tax and telling you can appeal in court if you have any differences.

Please help...
