Shocking service

I am extremely frustrated, I have been trying to contact Telkom since yesterday morning, I've made numerous calls and sent emails no one can assist me. I've realized that Telkom does not care about providing proper customer service. I received a call from cell connect regarding my upgrade on 23/10/2018. I accepted the offer and then change my mind the next day which was 24/10/2018. I did report this via mail and attempted to call however I was constantly transferred to different departments who could not assist me. This morning I get an SMS regarding delivery, I mentioned on my email I want to change the device! No one responds. I am at a point where I do not want to upgrade with Telkom and I am considering cancelling my current contract!! Can someone competent call me by 10am today?????
