Tds on foreign payments

Dear Sir

We have a foreign payment for which we received the bills in 2013 booked and paid tds (10%) on the same in 2013 however the payment not made during the year due to some issues. Now we are processing the payment but due to change in dolllar rate the amount increased by Rs.7000/- and tds changed from 10% to 25% now. What will be the impact of tds on the payment. Please suggest.
