Massachusetts has a specific auto-renewal protection law: the Chapter 93A + Auto-Renewal (Mass. Gen. Laws ch. 93A). This gives you powerful rights when canceling subscriptions.
Mass. Gen. Laws ch. 93A
Penalties: Treble damages under Chapter 93A for willful violations
If a company in Massachusetts didn't clearly disclose auto-renewal terms at signup, didn't get your affirmative consent, or makes cancellation difficult, their charges may be unlawful under Mass. Gen. Laws ch. 93A. SubScrub generates demand letters citing this specific law.
