That’s so funny, I did the exact opposite at my company. The nastier you are in ticket the slower we were to respond. Eventually word got out that if you’re polite you can get answers from the CEO. If you’re rude, you go to the back of the line and don’t have a chance of talking with anyone beyond tier 2. It took a couple years for everyone to “get it”, but it mostly works now. We only actually ever got 1 letter from someone’s family attorney (read: the customer’s sibling). We just sent a FU nasty gram back on letterhead from our huge multinational firm signed by a partner and we never heard from them again.
