I was overcharged for priority package today. Caroline call @360 6442083


I am so disappointed that his female has still not been trained in the art of delivering mail. She is too lazy to walk to my front door when she knows I am home. My car is in the driveway and I have 2 dogs that bark to let me know someone is there. It is such an inconvenience when ordering gifts because I never know if she will deliver or not. Normally she crams it into mailbox until now the mailbox is distorted to the point of having to slam it shut and it sticks. But she’s far too lazy to be doing this job . Hurry up and replace her. This is the 3rd complaint!


Mail carrier need glasses as he missed the mail box and judged that it was not worth to make the delivery but just posted for excuse ""Delivery Attempted - No Access to Delivery Location"". WHOA ! What a dedicated employee!!!!
