Services not requested inside the bank has to be deactivated inside-money making scheme

Every Friday I get notifications about my bank balances via sms that I get charged for. I did not go into the bank to activate this service and upon trying to cancel it I am told that I have to go into the bank to do this as this is a security feature. I told the lady that I'm not able to physically go to the bank, but they just refuse to assist. This is one more of Absa's schemes getting more money from their loyal customers who stuck with them for years.
