No after sales service

I keep calling the call center and can't seem to get through. I want to return your device and I need someone I can talk to to come and collect it. I have been calling from the day I received the device and have sent emails with no response. I don't know how else I can be in contact with anyone cause telkom could also not help. When the call center agent offered the package to me on the phone he did not explain that I will be dealing with an agent and I am not happy with the devise he offered me, he failed to explain that it will be operating differently from the one I currently use and lastly I am not happy with sell direct as the agent I would rather contract with telkom directly.
