Income tax deposited against wrong code

Dear Sir

We had deducted TDS in FY 2013-14 Q4 as follows 

Against 94c   Rs 25000.00

Against 94J   Rs 20000.00

But while depositing the amount  the challan was prepared as follows 

Against 94 c    Rs 20000.00(challan 12345)

Against 94J     Rs 25000.00(45321)

The correction should be made like this 

94c - Challan No 12345   Rs 25000.00

94j - Challan No 45321    Rs 20000.00

Now how can I correct the challans ? I appraoched to bank and Asseing officer (ITO) they expressed inability . 

Kindly help.

Thanks in Advance
