refund processed by it is less than we claim

Sir we file a individual return of it
In which tds is deducted according to 26as is 14281
And in it return we made a tax of 6460
So. We claim. Refund for 7820

But now judgement passes u/s 143(1) and they are calculating with tds 10900 only. But 26as is showing 14281
And the passed refund of 4550 with interest interest of 110

So what we can do. Now.... For refund of remaing tds??
