MOBILE ACADEMY WASP SERVICE - DEDUCTIONS WITH NO SUBSCRIPTION OR USE

I am on a cellphone contract and I have noticed that my airtime which I did not use will be used up in just a few days, which made me worry. I then did research where I was informed that some WASP companies activate these fees and then it gets billed with Vodacom, by deduction off monthly allowances. I was informed to sms to a certain number to see whether there are any WASP service providers doing this against my account with Vodacom and then to deactivate them. I received an SMS today that Mobile Academy was unsubscribed with immediate effect. HOWEVER my issue of grave concern is that I never subscribed and that I NEVER used their services, therefore why did I have to pay for this and to which extent was I financially impacted on due to this ***** service. I want this matter resolved and refunds provided or I will need to deal with the ombudsman on this matter. Thank you
