Unfair handover of account without proof of contract

I am extremely disappointed with how Planet Fitness has handled my membership issue. I initially signed up for what I was told was a 12-month membership. When I tried to cancel towards the end of that period, I was informed that I was apparently on a 24-month contract — something I never agreed to or signed for. I immediately disputed this and requested proof of my agreement to a 24-month term, such as a signed contract or call recording confirming my consent. Despite several follow-ups, no proof has ever been provided. Instead, the matter has now been handed over to debt collectors, even though the alleged contract remains unverified and disputed. This is unacceptable and constitutes unfair treatment. Until Planet Fitness provides clear evidence that I agreed to a 24-month contract, I will not acknowledge any debt related to this matter. It is unreasonable and ********* to hand a consumer over for collection without providing proof of consent. Desired Outcome: Immediate withdrawal of the account from debt collection. Written confirmation that no debt exists until valid proof of a 24-month agreement is provided. An apology and assurance that Planet Fitness will improve transparency with its contracts.
