Cancelled Twice but Money Kept Being Taken, Now Threatened With Collections

I signed up with LA Fitness in March then 3 months later decided to cancel the membership because of lack of use. I tried to cancel the membership twice but they kept taking money out of my account. I had to change my card number to get the payments to stop. They are still saying they never received the cancellation and now are threatening to go to collections with it. I am currently in the process of buying a house and don't need anything negative on my credit report. What should I do?
