—>Registering an official gripe against a company need not involve a trip to the post office. The Federal Trade Commission has an online form you can use, too.

While the FTC does not resolve individual complaints, filing a complaint can be an important first step in making a public record of company misdeeds.

Moreover, the threat of making such a complaint, and then providing documentation of it, can be a bit of a stick to wave over a company's head for consumers involved in protracted customer service battles.

File with FTC Electronically.
