this is to anyne who would like to response:
My story is this: when I used my merchandise certificate in this store, the cashier or must be the manager told me that my certificate has theft issue. That time they let me use it, buy something and I went home. When I got home, I decided to straighten this out and I called the Loss Prevention dept. of the store to straighten out what that issue is. I was connected to the department but no LP agent or anyone answered. The next day I called againl, asked to be connected to the LP dept., but no one answered again. I would like to straighten this out because I am going out of the country soon. It has been almost a month now since that time and nobody has contacted me. In your posts, you said it can take days , months or years. I would like to know what I should do about this before I leave to go abroad. As I said, I was at the store and they didn't do anything to me. Thanks for your help.
