Planet Fitness blood sucking tendencies

I joined planet fitness in 2019 on a 1 year contract with my wife.Covid hit and everone was on lockdown.The contract ended during lock down and they have unilaterally extended the contract.To make matters worse,they closed the GYM closure to my house and i have got to travel 8 km to go to the GYM.I dont have a car and that means i have got to walk 8km to that gym My wife and i today received an email from Landau to pay 27k for a service not rendered. What must i do to stop this madness,they have blacklisted me and they messing up with my life Iam angry with these monsters
