Why need to argue? Basically adam3199 is always right. Because he is a customer.
papa2 is basically a seller. Even it is not for business and clearing junk, it still consider a seller. The person who bought from you is a buyer, which means customer.

Maybe the graphic card is not faulty, because I face problem where the graphic card is not working in some mobo or had restart issue. So, if buyer demand back for the refund, seller should pay back full if it still in personal warranty period. Why pay 50%? In this case, buyer sure feel cheated.

No matter the card is working or faulty, buyer deserved the rights to refund if in personal warranty period. Also there is no need for apologize if the seller willing to full refund.

Now papa2 should apologize to adam3199 due to not refunding when the graphic card is not working on adam3199 mobo.

I'm a seller myself and I always feel customer is always right.

Now the easy state that papa2 just apologize to adam3199. Altough "sorry seems to be the hardest word" by elton john, but you didn't full refund in the 1st place making buyer feel cheated. Buyer had spends time and petrol which can't be claim back.

If seller didn't notice it was faulty before, then it is seller fault. Be a responsible person, and learn to respect.

Dun be so cruel. papa2 deserved the 2nd chance. If he apologize, we should forgive him and give him a chance. Everybody did mistake.

If papa2 apologize, I guess adam3199 will forgive him.
