Waka tv *****

I joined Waka tv with the hope of being able to see the world cup rugby, which waka tv couldn't offer, that's why I canceled my subscription by email and asked them to please not renew my monthly subscription, but I get no response from them, I could not use their program, and therefore unnecessarily give the money every month 3 months later and every month my subscription automatically renews regardless of my request not to renew subscription
