How do I refund a refund?

[Asianablue007]

Seller refunded my money 'cause my item didn't arrive and then after a bit it did arrive; so now I need to refund the refund! How do I do that?

You would need to sent a separate family/friends payment.  Just be aware that this would not be linked to the original purchase and refund transaction, but just a gift to the seller.

[Whac-A-Mole]

you can ask the seller to send you an invoice.
