Increasing Spend Limits Without My Permission

I am very upset at the appalling service from Telkom Mobile, you guys are increasing my \future spend limits\" without my permission, I called the call centre to sort this out. I had to wait 8 minutes to speak to an agent only to be given misleading messages saying that she couldn't change the future spend limit as it wasn't loaded on the system as yet, then she said as soon as it is loaded it will be taken off, then she said I will have to call in at the beginning of next month to have it sorted out. Her name was Noxile or Xolile, I called at 10:55. I then asked to speak to a supervisor she then put me on hold for 15 minutes and still no supervisor. In total I spent a whooping 25 minutes on this call with no resolution and misleading information. You guys need to sort this out and stop increasing my spend limits without my permission."
