Planet service non existenced.

So I when I was 17 (2008) I joined Planet Fitness Montana, but I was a minor so It was on my mother's name the contract. Then when the contract was done after 2 years myself and my mother went back to cancel the contract. We spoke to the manager at the time apparently it was sorted. Only to find out that in 2018 myself and my wife wanted to join planet Fitness in our area and then came to a shocking realization that the contract of 2008 was never stopped and that same contract was moved over to my name. Whereby no one in the planet Fitness side would think of trying to contact me after I even gave them my details at that stage. 2019 I sent them a email launch a query with reference nr Pf*** but even then no response. Then another 4 years go's by then all a sudden I must contact attorneys with letter of demand. To make a better I cannot even remember in signing for a contract in 2008. Even better the attorneys can not even produce the contract. And is told I should get it. Funny enough I went to a planet Fitness in 2019 trying to sort it out but even then it went nowhere. Because the branch in Montana moved and they don't know if they still have the paperwork. So from 2008 to 2022 planet Fitness couldn't assist me. But I must pay for a service which I didn't even know I had.
