Alright, I'm in a bit of an odd situation. I sold an unlocked phone on ebay about a month ago. This particular model was a Motorola a630, a flip camera phone with a qwerty keyboard. I bought the phone myself off of ebay and used it for a few weeks but I was unhappy with it. As it turns out these phones have really poor reception, its just a flaw in the design. When I was in my home network it worked fine, but if I got out into the country it just couldn't keep a signal. After looking at reviews of this phone I saw several complaints about this so I chalked it up as a loss and bought a different phone. Well, the a630 sat on my desk for a while and eventually I decided to resell it on ebay. So the auction went and there was a lot of interest and after seven days there was a high bidder and lucky me.. he payed about the same as what I bought it for. I was so stoked. I only lost like $10 or something. Fine with me. So I get the money from the buyer and ship it out to him. When I ship it it works fine, its unlocked, it just gets poor reception in remote areas. So he has it a week and emails me. He says "this phone isnt unlocked, i want my money back." I of course responded that it WAS unlocked, I'd used it myself.. and I mention the poor reception. He acknowledges that he is in a pretty far out in the country and doesn't get much signal... but says that he's unhappy with the phone. He asks for his money back. I, of course, tell him no. There's nothing wrong with the phone, every a630 he buys will be like that and I didn't offer a "satisfaction guaranteed or your money back" in the ebay auction... so he bought what he bought. If he didn't know what he was buying originally, that's not my problem. He responds and I quote "How about minus the shipping costs?" I still tell him no. As ifI'm suppossed to eat the ebay and paypal fee's, eat the shipping and then resell it because he didn't know what he was buying. I thought all was said and done until today when the phone arrived at my doorstep. No note, no nothing.. just the phone as I shipped it out to him. What am I supposed to do now? Do I have an obligation to do anything?
