refund instead of sending the rock

for no reason whatsoever I was issued a refund and the company never told me why.

KP Aquatics: It’s because you order 3 lbs of airfreight rock which has minimum of 10 lbs and I also needed the Southwest Airport Code. We refund orders automatically if this occurs.
