A mailbox was installed at my home. Packages have previously delivered #9400110898825013044559 on 6/22. Another package arrived In Sumas for delivery for the second time by USPS on 6/27, out for delivery #9400110200830758195733 on 6/27...email updated indicated undeliverable address. Being returned to sender again. Postmaster needs to be trained on deliver service to his clients in Sumas, WA. Totally unacceptable customer service by USPS Sumas WA 98295.
