Unauthorized deductions

For the past year these so called banking institution has been deducting unauthorized fees from my account. I visited the branch in Stellenbosch and were informed that it was sorted. This month end the same thing happened again. Pathetic. These deductions were for MU PRIMARY SMS AND EMAILED INFO. i never agreed to this, nor have I gave permission for them to do so. Please Standard Bank refrain from deducting these unauthorized fees. Don't contact me, your help desk are clueless and non existent. Keep getting cut off. I'm not interested in emailed info nor MU PRIMARY SMS
