This is the worst! We are so sorry about this inconvenience, please double check that the shipping address for the order was entered correctly.
The next step we would suggest, if this is the correct address, would be to check with your local post office as to exactly why this package could not be received! If they don't have answers, shoot us an email at firstname.lastname@example.org so that we can go ahead and send another package out to you.
We generally would suggest trying another address, but if the original is 100% correct, we can go ahead and try that one out again!
We look forward to getting you those shades!
