You are formally documenting for all future processes that you have filed a complaint, and should include relevant contracts, receipts, correspondence, and support materials. This can be enough to encourage the business to be more responsive.
So it's a low-cost first step that can trigger mediation or settlement and help resolve your dispute (and contribute to broader consumer protection). It's a quick way to signal to the business to work with you.
Submitting a letter or formal complaint can prompt the AG (sometimes) to contact the business in an attempt to mediate or resolve the issue informally. The AG also often offers informal mediation services though some division. The AG’s office sometimes starts investigations based on complaints from the public.
