Ebay problems, PLZ HELP?

The same thing happened to me, but I don't know for sure if that person really has the item and they are just jerks. You should always have a tracking number. It costs .80 cents. If you don't want to pay it, charge them for it. Some people are jerks and since they know that you did not provide a tracking number they will say that they did not receive it. So, then they open a case and you lose because eBay does not know who to believe. In this case they will favor the buyer and not the seller. Next time have a tracking number. You can call (it's better if you call) and tell them what happened. But I really doubt they will favor you. Sorry, I know how it feels. Also, when you sell an item, go to where you select who gets to buy your items. Ex. you get to pick how many posiitve feedback a buyer hads to have in order to buy from you- this way you know that this person is honest.
