This may not be the best forum to ask this but I figured the people here change phones often so maybe someone has had this happen. September of last year is when I joined my fiancé's AT&T plan and we made it a share plan. That day I got a Galaxy S3. Then on October 1st I brought the S3 back and got an iPhone 5. A few weeks ago I used her upgrade and got a Note 2. Her upgrade status correctly says that she isn't eligible but my status says that I am eligible for an upgrade. When I went to use her upgrade at Best Buy the guy told me that my line had an upgrade but I used her's assuming that it was just a bug and it would be corrected. Weeks later my line still shows an upgrade. Has anyone had this happen? If I go and upgrade again and AT&T catches it can I just bring the phone back so I don't get charged?
