Disappearing data and airtime

Its a new year and it would seem that vodacom would continue with data and airtime theft, it doesn't help to reason, and why is it that vodacom allows third party companies to harass their clients with **** purchase notifications, keep getting notification that I have used out of bundle airtime when I'm not even on any network apps, I have blocked any access by these companies from taking airtime from my account but to no avail it just continues really disappointed in vodacom service
