Call 1-800-GO FEDEX
They will know what is going on, and they can fix it.
Apparently the address you gave is a business. The business was closed so they did not attempt delivery. The package will be attempted once the business is open... probably on Monday. Otherwise, you can call FedEx and pick it up at FedEx on Friday.
Sounds like they think the delivery address was a business that was not open. Double check that address.
answer from "Jake" is correct.....was the address you provided a business ? they will try to redeliver 12/24 BUT it could be anytime of day from 8 am to 10 pm
