********ly subscribed to services

I activated data share on the MTN mobile app. Immediately thereafter I was spammed with SMSs advising me that I had signed up for numerous (around 8) content services ramding from R7 to R15 per day.... who gave MTN permission to do this? It's **************** and in complete contravention of CPA not to mention *********. I had to dial *136*5# around 20 times to deactivate all these services. Unacceptable
