According to DHL Commerce Tracking my shoes from Masseys were left in the parcel box at my address, 258 Ruth Dr., Pacific, MO 63069; however, there was not a key in my mailbox to the parcel box & the keys were already in the parcel boxes & empty. As usual, if it's not the routine route for the carrier they often leave my mail at 258 Millstone Village Dr., Pacific, MO 63069 & I believe this is the case once again. They also said they left another package of mine from Hanes in the parcel box. Evidently the postal carrier does not know the difference in Ruth Dr. and Millstone Village Dr. These are items I need. Can you see to it I get my packages please?
