Refund And Cancel Any Subscription

I discovered today, October 23, that Dramacove charged me twice for a subscription, with two separate pending payments of $19.99 each, totaling about $40. I find this unacceptable because I did not sign up for a recurring subscription and I certainly did not authorize being billed twice. I had only tried Dramacove once before, at a discounted price, just to test the service. At no point did I confirm or press any option to renew or resubscribe, and I did not receive or approve any clear notice that I would be charged again, let alone twice on the same day. I request that both $19.99 charges be fully refunded and that any active subscription on my account be cancelled so that I am not billed again in the future.
