What to do when self assessment tax was paid under another pan?

What to do when self assessment tax was paid under another PAN and name instead of the person actually liable to pay the same and the ROI of both the persons were filed through E-filing and the payment was shown in the ROI of the actual person who is liable to pay, as paid. In the ROI of the person in whose name and under whose PAN  payment was made,no refund was claimed nor it was shown as paid. The ROI of the person who is actually liable to pay self assessment tax was processed u/s 143(1) and demand raised. The other person's ROI is not processed so far.
