I am writing to you about one of your members, <company/individual name>. <dealings with company/individual>. This kind of behavior is unacceptable, and reflects very poorly on the <profession> profession, so I am writing to bring it to your attention.
I must insist on some action from your organization to address this situation. That may mean <moderate action>, or something as drastic as taking legal action. Simply put, this kind of behavior on the part of a professional is intolerable under any circumstances.
Please contact me about this situation, or if I can be of any assistance in resolving it. Thank you for your time and attention.
