Broadband or Utility Complaint Letter That Actually Gets a Response

The broadband has been down for three weeks, the customer service chat went nowhere, and the standard complaint form asks you to describe the issue in 150 characters. This drafts a formal letter that cites the correct process, states the resolution clearly, and sets a deadline, without sounding either threatening or helpless.
