Wow, I really can't even believe I am dealing with people like this. I sold a GBA wireless adapter to some woman on ebay. This is my first problem in selling on ebay since 1999. This women has now opened a case against me and my perfect account because the wireless adapter will not connect to some wonderspot thing that is supposed to be an event in some store because she said her son said that the adapter can download pokemon to the game from a retail store. Keep in mind this is a GBA item and is long discontinued by Nintendo. I have been going to pokemon events since 1999 and I do not think Nintendo ever even had an event that used the GBA wireless adapter to download pokemon from a wonderspot. She is accusing me of not disclosing features of an item. I specifically disclose in my auction that I do not do returns or refunds for any reason and I tested the adapter before I sent it so I know it works. I also have in my auction that the buyer must know what they are buying and that I am not responsible for system incompatibilities.
WWonderspot did allow you to do some stuff with the wireless adapter like get a ticket to the island to capture mew, download manaphy, maybe download celebi and alter altering cave to capture good pokemon. Besides the Nintendo events, toys r us had them in store for certain periods and events. I believe a friend of mine was a "gym leader" around this time and I can ask him.
All that being said, the reason it won't connect us because Nintendo stopped supporting it in like 2006. The primary function will still work. I'm sure he could connect to another gba wirelessly. That is what it's intended for, the wonderspot was just a time limited bonus.
So just tell her it does work, she just needs to go back in time 8 years to when that particular function was available.
Does she also expect the Dreamcast phantasy star server to be included with the auction? If you didn't list it as working to download from something that doesn't even exist, I don't understand how she has a case?
