Are you in the EU? If yes, every country here has some form of enduser protection agency. They try to resolve it with them through normal means, assisting you. Here in germany the “verbraucherzentrale” posts online about such stuff, if it is a bigger company, they even contact public media, and if more people are effected, they sue the company, not only over the damages the specific customers had, but also e.g. false advertisment (like its here), contract breach and malpractice. Idk if such things exist in NA countries tho
