Renewed my contract without my permission

<p>Ruffly 8 years ago I walked into Planet Fitness and they told me that my contract with them are over and asked me if I want to renew it. I told them not to renew it, but they must have renewed it, because since then they're bugging me about my account. Over several phone calls and an email I told them that I never renewed my contract. This happened to a friend of mine aswell. Now they're going to take legal steps if I don't pay them in the next 3 days.</p>
