Wait and see what happens with the plant.
I agree with prior comments though, this is a bad time of year to be buying tropical plants and shipping them through the mail. Especially if the plant is delivered to a mailbox instead of (for example) a warm office.
Live and learn; if it dies, it would not be reasonable to expect a refund of any kind from the seller, since you agreed to buy it in winter and ship it to the northeast USA. If by some miracle it lives, consider yourself lucky.
Never order plants to be shipped to you at the end of the year after the USDA first frost date in your location and the shipper's location (or in the beginning of the year before the USDA last frost date in your / shipper's location). Not unless you are willing to pay
a lot extra for express shipping and special packaging. Even close to those dates you should be very mindful of weather forecasts within 10 days of the shipment date. If you are close to a holiday where there is usually a lot of package delivery, you should expect significant shipping delays.
