I got scammed and had to make a recall for my express mail that I sent out yesterday. I went to my post office, and people who work there tried their best to help me out. They made phone calls to IN post office to get my mail stopped. Everything turns out fine. They helped me save $3000. Warning to you all, especially college students, becareful of all online job offer jobs. It might be a scam. Thank god, thank to the post office men!
