MTN unauthorised charges

have been billed for "Content Events" never requested or agreed to. I have been into MTN in Kenilworth Centre twice and the consultant tried to assist me, but was informed by MTN HO that no reimbur*****t was possible. The enquiry no *** has been closed, but the matter has not been resolved. Surely it is ******* for MTN to allow charges to be made to accounts in this manner. I had to set my account limit to zero to stop further charges, but I see it is still being attempted. Today's message: REMINDER: "Yello. Your subscription tpo PockitTV at R 5.00 per day will be renewed daily. To manage dial *123 #. Also: Yello Rugby Daily and MTN Arcade. I have never requested or used any such services. If I am being charged in August alone R 87 plus VAT, imagine how much this adds up to for all MTN customers??
