Review Unauthorized Subscriptions

what is this unauthorized subscription notices i keep on receiving. i don't subscribe to any of this thrash and yet they keep on running on my account. I buy credit and in a short while it gets finished all because you people sign me on some of your products which are irrelevant and useless to me which end up consuming my data. I am not interested in any of your products so please stop signing me on your products without my consent. this is totally nonsense. how do you people subscribe me without my consent.stop this rubbish.
