Keep calling them

I made the mistake also.I receive the approval notice on April 25, and then I found the name wrong. I called them. The officer said he would try to look at it. I called on May 1, 2007 again to confirm it. Another officer took the call and told me they couldn't change it and have to refile. I was so frustrated. I called them again on May 3, 4. Different officer has different answer. I received another approval notice on May 7,2007 with correct name. I have no idea what is going on. You keep calling them. One of them will change it.
