Although it took them time to reply, after a couple of insistent emails, they obliged in not only cancelling the subscription but they also complied with my request of refund. My recommendation to the vendor is to make the purchase process more transparent as well as using a proper email correspondence so that their initial subscription confirmation with option of opt out yes not end up in the junk mail that you will miss and end being automatically a subscriber.
