No. Was your order scanned inbound to customs NY or was it at sort facility Jamaica, NY? Makes a big difference. If it is at the sort facility call USPS and open a lost package ticket and they will usually find it pretty quick. If it has simply landed in NY, it is in customs and it sounds like it is not leaving, expect a LL at some point.
Do you have knowledge of ramifications of seizure? It happened to me once about 9 years ago....I got the letter from Feds instead of my product and that was the end of it, as far as I know
