Disgusted with Showmax

I am disgusted with Showmax. I signed up for a 6-month limited offer. NEVER was any cancellation policy pointed out to me. And why should there be one if I signed up for a LIMITED 6-MONTH SUBSCRIPTION?? It is a low form of making money when I have now been debited after the 6 months "because I didn't cancel my subscription." This is a ******* - and DISHONEST.
