Let me first apologize for the way I put it. After reading it today with cool head I see that I did not choose my words right and I should have not mentioned. I sincerely apologize.

Problem is, just the add with additional pictures costing me 10 CHF plus the charges of 5% for the buy now that he did, so it will be more than 20 CHF. Plus, he ruined my auction and I will not be able to sell it before my vacation and leave it for September, which I did not want in the first place. Plus I had serious bidders who would have bought it in 2 days and pay for it without asking where was it made after the auction. This sale would have been my beer money for the holidays and now I don't have it because of a irresponsible person.

Yes, I mentioned this to him that if he had done it to a Swiss person I highly doubt it that he could have had it his way on a situation like this. Problem is, I don't want his or anyone's money that I need to push or treaten for, when I do business or small sale I like to be happy and the buyer to be happy. But your point is good.

Indeed, there are more important things than to argue for a situation like this, but it get piss you off.

Yes, I think too he would have been quite scared if I pulled that scenario. I did not want any conflict so I let it go. I just said no more bidding and buying from me in the future, not even questions. I don't want to loose time anymore on deals like this when majority of people use the service as it was intended to.

Just had another thought: you could of course give him negative Bewertung which you are fully entitled to do, as well as putting him on your "blocked" list so that he can never bid for one of your items again. Our sympathies - it is not an enviable situation to find yourself in

I searched through the option and can not find this option, how can I do it?

OK here goes :
Firstly make sure you are logged in = might not work if you are not.
Secondly, go into "Mein Verkaufen" [finding three lines of options]
Thirdly, bottom option, middle, is a "Schwarze Liste" where you can
put someone on your black list after giving a valid reason. Good luck.
If you need more help, please let us know.

I succeeded, thank you!

Very Welcome!

Well, then you should have told him it cost you CHF20 & you want CHF25. Seriously as was said above, you have to pick your battles. Sometimes people do stupid things, but life is too short to let them get you all p!ssed off.

Put the thing back up for sale for CHF25 more.

Good luck! I hope you get it sold in the 6 weeks before your vacation.
