Is ST applicable

A service provider is rendering Commissioning and Installation services to many including SEZ.  They have availed input credit but not maintaining separate accounts.  The dept. claimed that the availment is incorrect and has to pay the ST on the exempted (SEZ) value.  They are for reversing the credit availed.  Dept's contention is that they cannot seek reversal of credit when higher revenue is involved in demanding ST on the exempted value?  Is that correct.
