mtn and Basebone taking airtime from mtn customers

I have recently discovered that I have subscriptions that I never signed up for. Because of these subscriptions every time I load airtime it disappears, I have called mtn and they say I have a subscription with basebone but they claim to know nothing about this "basebone". I've called and emailed a jacques from waspa who "enquired" about the subscription, nothing. I called basebone and they told me to "file a legal inquisition", the Chinese lady (I assume) kept saying she doesn't understand a word I am saying and kept on telling me I need to send a "legal inquisition" to find out the details about this subscription. They have been taking Between R8 and R15 a day when I have airtime. Mtn and Basebone must be running some shady business that I don't know of.
