Disappointed With NetShort, Can't Cancel My Subscription

I have a weekly NetShort subscription that I am unable to cancel, and I have been charged even though I am trying to stop the service. I subscribed and tried to cancel via the NetShort website, but I cannot log in anywhere to access my account and complete the cancellation. My account is registered with the email address jenaju***[email protected]. Today, when I wanted to cancel, I realized that I cannot log in to my account at all, so I have no way to manage or stop the subscription myself. Because of this, I am being charged against my will. I tried to submit a complaint to NetShort customer service, but I have not received any response. I request that my NetShort account be canceled immediately and that I be refunded for the charge taken today, as I am unable to log in and manage the subscription on my own.
