That sucks. I had an issue once where I accidentally put my old zip code on my address to get something from overseas. I checked the status online and it said "COULD NOT DELIVER, RETURN TO SENDER" and I almost cried, and then I got it anyway, apparently the post office figured out where it was meant to go by the street address and then just rewrote the zip code to the correct one. Anyway, hope it all works out for you.
