subcription cancellation

I'm nor praising you. Unsubscribe me. I want to unsubscribe from the pro version of the program. How do I do that? Like I don't want to pay the money next month. I don't mind if you keep the money you already have, but please unsubscribe me from your premium program. Like, unsubscribe me right now. Why aren't you responding??? How do I get a more direct mode of contact.
