Tds not fully taken ay 2017-18

I filed my return for AY 2017-18 on time.

I got intimation of 143(1) today morning. There was a demand of 21K instead of refund  of  59k.

Two TDS of 22k and Rs 55555 which are appearing in 26AS - the amount of tax credit given is zero. Beause of this there is interest under 234B and 234C.

I doubt whether they check personally the 26AS.

My question is if i send for rectification the interest will be reversed or not ?
