Unfair contract term and never ending escalations

Telkom and its billing department have failed to resolve my issue around my contract term. It is end of the year now and for the past 4 months I have been told lies that they have resolve my case. Every time I do a follow up I am told that that matter has been escalated to the billing department and that somebody will contact me to resolve the matter. Nobody contacted me and nobody cares. I am planning to buy magnetic posters to put on my car and tell the whole about the terrible service from TELKOM. I am fed up, I want out!
