Request to waive the interest on late payment u/s 201(1a)

Hi…We received intimation and demand notice under section 200A and 154 for late payment of TDS for 26Q3 and 24Q3. Due to banking server down on 07-11-2012 we paid the amount on 08-11-2012, for one day delay department levied interest at 1.5% for 2months under section 201(1A). It costs us nearly 2 lakh. We have taken a declaration from bank stating that it was their problem. Is this evidence suffice to go to department and request them to waive the interest? Will they accept??
