Have been out of town for several months. Mail scheduled to discontinue forwarding 11/01/21. Expect to be delayed returning to St Helena Island. Please hold mail delivery until 11/15/21. I will pick up upon my return. Thanks; Joseph H Eber, and Joseph H Eber Jr. and Associates.


No answer on phone during open hours. I need a package with tracking # 9114902200789042156912 to be delivered to Laure Puccini, 72 Janette Dr.,St Helena Is., SC, 29920. Informed Delivery tells me it was out for delivery on the 4th and then it was waiting for a scan on the 5th. So please tell me where this item is, it has not been delivered.


Received some type of note from USPS on my front door steps but it rain all night and can not make out what it said. Think it said some thing about sorry they missed us. Howard Whitehead 57 View Point Cir 29920


Horrible service, I submitted at the PO a forwarding form on Sept 6, 2018. It was until oct 25tb. I have yet to receive my mail.
