Gym company *******

I have been trying for the past 6 months to cancel my Gym company membership from their Winchester branch. First I lost my job, but for as long as I could I kept on paying my account, when I ran out of funds I tried to cancel, sending many emails and receiving zero response. Now I am working but have relocated to Cape Town, this is my 3rd month here, they don’t have any gym companies down here and still trying to cancel and there no responses but the debit order goes off every month. I’m so tired of paying for services I’m not using
