I-131 Denied- Help/Suggestion Needed

My I-131 (Advance Parole/ Travel Document) has been denied as a part of Green Card Processing. USCIS says in the letter: "A review of USCIS records indicates that you departed the United States on 11/10/2017, while this Form I-131 was pending, and before your Advance Parole Document was issued. Therefore, the Form I-131 is considered abandoned and must be denied." This reason is false- I never traveled outside US since 3 years, why would I do that? I don't know how to I handle this situation. Anyone- any ideas or heard similar cases like this? If USCIS assumes that I have traveled outside US, I am damn sure they will deny my I-485 too. I am still shocked how did this even happen. Your help, suggestion or any words would be appreciated. Last edited: 11-Jan-18 02:07 PM Last edited: 11-Jan-18 02:08 PM
