I bought recently some item off eBay. The item turned out to be 'not as described', so I returned it to the seller. The seller took it back without any problem and refunded money in full.
However, eBay now shows that I have to pay for this item. What should I do in this case? I guess that if I ignore eBay, I'll be left with black mark for unpaid item? The seller already gave me positive feedback, so what should I do in this case? Should I just mark it as 'payment sent'?
