Horrible service

My contract with the gym company ended in 2018. I only became away of this last year during the pandemic. And during these times when the gym was not operating, they were debiting my account. I reversed those payments of the three months. I have told so many of their consultants that my contract ended in 2018 but this company insists that I must pay 600 and get a new contract or pay 1000 within 5 days for them to cancel a contract that eneded in 2018 otherwise they will blacklist me. This is *********. I'm so sick of this gym, i would never recommend it to anyone. It is cheap because of *******.
