I sent them pictures of mine when it arrived with a broken door (I bought a scratch and dent for $99 shipped). They refunded my entire purchase price, and told me to throw the unit in my dumpster. I took the refund, and had a new door made out of solid cherry:
Honestly, if the damage on the top isn't huge, I'd just use some touchup paint. Maybe they should send you a new door instead of you having to ship the entire unit back.
