Hello, My order # and supporting documentation are attached. I ordered five books on 08/21/2021. Three of the five books I ordered on 08/21/2021 did not arrive but the tracking number says it was delivered. The three books are: Isbn10: [protected] Isbn13: [protected] Condition: Used - Like New Quantity: 1 Title: Civil PE Practice Exam: Water Resources Depth Version A $14.94Isbn10: [protected] Isbn13: [protected] Condition: Used - Good Quantity: 1 Title: Civil PE Practice Exam: Water Resources Depth Version B $19.35Isbn10: [protected] Isbn13: [protected] Condition: Used - Very Good Quantity: 1 Title: PPI PE Civil Companion for the Sixteenth Edition - A Supportive Resource Guide for the NCEES PE Civil Exam $7.16 The USPS tracking # is 9449037902643856494925 which says they were delivered on May 24, 2021, to an address in Philadelphia (which I believe is where booksrun is based). So not only is the delivery address associated with the tracking number incorrect, it is also impossible that the books were delivered on May 24, 2021, since I ordered on August 21, 2021. I desperately need my books to study for my upcoming exam, I have sent an e mail and a message to booksrun in hopes of resolving this issue. I did not hear back yet.
