Hi I bought an item on ebay on the 9th. I emailed the seller on the 10th. She said that she would mail it out saturday. I emailed on sunday asking if she had sent it out. she said i will send the tracking number on monday, i am not home this weekend but she listed 3 items right around the same time that the sent me that email. I emailed today and she has not returned my email. what should I do??
