Still not fixed

So not to mention that the SM department has never gotten back to me regarding my first complaints that I eventually sorted out myself with their sales department. Now the sales lady that helped me has put me on a more expensive plan after promising that I would go on the same plan (Simple Plus). Now according to the center this plan is no longer available. So please tell me how can I be held responsible for Telkom's inability to fix their own problems and offer empty problems and broken solutions.
