This level of incompetence is just unbelievable

Reported on two previous occasions. Two of my non contract phones that is only used on home wifi, NEVER on mobile data is charged R0.01, that's correct 1 cent per month 'out of bundle data'. I'm in my seventies. You probably will not bankrupt me. I am just amazed at the absolute incompetence that you cannot sort out this irritation. Don't send me automated messages asking more info. I have twice before furnished you the numbers. It's simple really. Catch a wake up. Do what you are getting paid to do. Please tell me why you cannot sort this out??? I've seen some silly stuff in my lifetime, this is just the most glaring instance of TOTAL competence.
