Interest u/s 234A B & C

Sir I face some problem regarding Interest u/s 234A B & C
Shortly I describe my problem
I file my ITR for AY 17-18 after due date.
I am a Salary employee.
My Total Taxable Income Rs. 660550 [ This include arrears received on 1-3-2017 ]
My Gross Tax Liability Before Tax Relief Rs. 58823/-
I claim Relief u/s 89(1) as per From 10E  Rs. 58823/-
Then My Total Income Tax Liability
after Relief                                                  Rs. 0/-

CPC  demands me Interest u/s 234 A          Rs. 2940/-
                                            u/s 234 B         Rs. 5880/-
                                            u/s 234 C         Rs. 2970/-

Sir please guide me is it correct demand, because my Total Tax Liability is Nil so why CPC demands Interest.

Thanks
