This phone number puts me in direct contact with a GYN Clinic. Has the PO become a joke? I just mailed an Express Mail Package which was never delivered in Seaford. It has been sitting there since last Tuesday. It contained a $5500 check legal documents for a time sensitive case. Today is Monday and it just sits in the Seaford Post Office without any attempt at delivery. I was assured I would get my money back. No supervisor was able to come to the phone. A clerk apologized to me. How can I contact a supervisor of delivery in Nassau county and explain what is going on? How can you leave an Express Mail package laying around in your post office for a week without taking notice? A phone number was clearly on the package. Please explain this situation. I want these idiots to be suspended or fired from their jobs, that includes the Post Master. Please tell me what you are going to do. EL815035263US Express mail number $23.85 cost. Legal costs unknown at this time.
