BAD SERVICE

I received a sim card that was and cannot be activated, i have called,emailed and whatsapped them for assistance but no one has even contacted me to talk me through to try and explain why its not working yet i have been BILLED for a sim card which is not activated. I went to Telkom to try and get help and they said that the sim isn't even registered. This is by far the worst service ever..especially because no one has connected to me to try and resolve it. When i call their so called Helpline number no one answers...it feel like a ****!
