Macfit Ömür Mall Charged Me for Second Month (Unwanted)! One-Month Contract Ignored

I bought a one-month package from Macfit at Ömür Mall. After my initial month, I decided not to continue, but to my surprise, they charged my credit card for the second month without my consent. I just signed up for a one-month contract, but they went ahead and charged me for the second month, even though I didn't even go once. I think the fee I paid was taken unfairly, and I'm really frustrated about this situation. Watch out to steer clear of similar situations.
