Unless you are doing something wrong and they can just explain to you how to fix it... Maybe they just wanted evidence you have a defective product before shipping a replacement. That is actually good customer service. And I'm not a fanboy of UV, I actually am not a fan of most of their products, in particular the scopes. Maybe the one that didn't understand is you, and because of it, you posted your mistake on the internet for everyone to get a good laugh. Sounds to me like you are jumping to conclusions for a company who was trying to help you...
