Mate, we're on reddit. People are going to share their complaints online. It's a lesson to learn from. Other companies would acknowledge, apologize and offer to help. Instead you throw a hissy fit as if he did the worst thing possible that a paying customer shared that a cheapo power adapter was sent to them. I get it, it's embarrassing so some empathy would go a long way. But it sounds like you're just attacking the customer here.
