I posted a 20 year old laptop on eBay and also described the hardware in the item description and also point out that the laptop is no longer usable for everyday work, because slowly…
Now the buyer complains about this: "The PC is so bad" and now he wants his money back.
If the buyer doesn't want to read the description, that's not my problem, is it? I also stated in the description that the PC is slow and I would not take it back.
Let him gripe
Send him the description of the article and remind him again that the device is 20 years old
Would point him to the offer description and then well. If he continues to complain, ignore it.
There's no right of withdrawal for him. Unless you lied, which is not the case.
Sales contract is sales contract. You are not obliged to do so. He must have been unlucky. If he threatens a lawyer, you don't need to worry. You are right.
No. The seller should leave the buyer alone.
