How to cancel a subscription without paying

[Guest]

Hi, I need help from you, I'm really stressed, and I don't know what to do, a month ago I activated a 7-day trial, I wanted to take a photo for my grandmother because she died, when I activated a 7-day trial, so I thought that after end of the 7-day trial, I'll have to pay for it, I didn't even know they would take my money every month, and I want to cancel the subscription, but they want a lot of money from me, and I don't have it, and I don't want to pay for it, I don't have a job,and the money they took from me, were my pocket money, should I cancel my credit card? so they don't take any money from me? PLEASE HELP ME
