NetShort Started a One-Year Subscription Without My Consent

Shortly after downloading the NetShort app from the App Store onto my iPhone, I noticed that a one-year paid subscription had apparently been started without my clear knowledge or consent. I barely used the app before deleting it, but when I tried to cancel the subscription, I was required to enter payment and credit card information.

I do not want to pay $73 for an app I barely used, and I feel that I have been put at a disadvantage because I kept encountering screens in the app asking me to pay. I do not believe I knowingly approved starting a paid subscription or entering my card information.

I have not yet contacted Apple Support or the app developer through the App Store, and this is the first time I am reporting the issue. I request that the one-year subscription associated with my account be canceled immediately and that I not be charged any amount. If this charge is already showing as pending or otherwise associated with my account, I request that it be removed so that the $73 is not billed to me.
