*****! A weekly 50MB bundle has been loaded without my knowledge or consent.

Good day, I received an sms yesterday on stating that a weekly 50MB bundle has been loaded. I checked my airtime balance and R10 has been taken off. I want to know how this happened without my knowledge or consent. It’s *****! I want this cancelled immediately and my airtime refunded. I also want to request that your spam sms's stop - please remove my number from your database.
