This week, we heard from a reader who we’ll call Mr. X. He works in marketing, and handles escalated customer service issues. He’s the guy you talk to when things go horribly, horribly wrong. He listens to your phone calls, and decides whether you should receive bill credits and other nice things. Mr. X has some very important advice for the customer service ninjas of Consumerist: please stop being jerks to front-line employees.
