ebay tells me my package was deliverd. i guess only the post office is aware it was not delivered due to 'animal interference'. so now ebay considers this a done deal and i have no product. ebay seller will say " the usps says they delivered it". unbelievable. i nor anyone in this house owns an animal, btw.


This is the best post office in CT. The staff @ the windows are very considerate and efficient. The customer service is amazingly awesome. If a best service award was ever given this is the Post Office that should receive it. I live in a different town but make the trip every Sat morning because of the service.


I went into the Ansonia Station post office to have an important letter postmarked with today's date. I went on the line and an extremely nice woman who works there took me off the line and helped me personally get done what I needed. Super efficient, extraordinarily helpful and friendly.
