What can I do? The Amazon website & USPS office said it's delivered Sep. 12th, I never received it. I went to USPS office and talked to the clerk & postmaster, they checked and print a record showing it's delivered, told me there is nothing they can do. The postmaster later told me he will call me next day, yet he never did. Went in today again and still get same answer - it's delivered - per their record. It's an order sold by third party but fulfilled by Amazon, and Amazon used the Fedex Smartpost + USPS service. So basically four parties are involved, who is responsible? I don't want to lose this $27 order!
