We run out of Coeur d'Alene, about 8 miles from Rathdrum, so there's no branch or drop-box here - a call gets a truck routed out to look at the door in person rather than quoting panel work blind. Bring a photo of the damaged section and, if you can find it, the brand or model sticker on the inside of the door; on a 2002-era door that sticker is usually still legible, which saves a trip just to identify the part.
If you're not sure whether you need one panel or the whole door, say so when you call. That's a normal question, not a sign you've done something wrong, and it's easier to answer standing in front of the door than over the phone.
