Bunch of ********s

I joined this Gym 3 days later the gym was closed I think for almost two months … I gave up after a month than joined another gym…so these people come back 3 months later saying I owe them money… so I was supposed to wait for them and pay the gym…. Last month I told them to stop going into my account and cancel the membership that never even started and refund my joining fee… but they still going to my account and they have not refunded me…debit order fees and massing up my credit….
