Antitrack subscription cancellation

Hello i bought the trial version of antitrack in august 5 , because it is 1 month free.But in September, 59,99 TL (Turkısh liras) = 10,13 USD will be allocated from my account.You said so, but I don't approve of that.I want my subscription to be terminated without any payment.I bought it for 1 month because it's free.I would appreciate if you help.
Have a good day.
