Amazon representative fail to add subtotal and shipping charges when calculating payment

I just sold a book with ID:113-4173364-9277864. The book is $71.99. But the Amazon worker forgot to add the shipping charges and the subtotal of the book when calculating the payment, making my  gains, which should be around $60, into a negative 4:07$(the shipping charges from USPS). Please check and correct the mistake asap. Thank you! The book I sold is Mystic Enlightenment.
