Yes. Contact the seller.
Ask for a REFUND not a replacement.
Refunds can be done immediately. Replacements , even if they do not take a side trip to Malaysia, can easily push you past the deadline for a Dispute, if one is necessary.
If you still trust the seller, you can then re-order the item.
Or you can ask her to let you know when that special one-of a -kind item is returned to her to work out how to start a new transaction.
Or you can keep the money and order from someone more organized.
If the item does eventually end up with you, you can repay the refund using Paypal's Send Money service.
