I PAID FOR A SERVICE I NEVER RECEIVED

It was on the 7th of December when i discovered that the unlimited free calling for 8ta to 8ta service was not active because i was unable to make calls even to 8ta numbers which was supposed to be free. I then contacted Telkom mobile in the same week and i was told they have sent my query to their technical department. I have made many follow ups and every time i do i am told that they will send emails to their engineering department and make follow ups and call me back with feedback. They have never called or sent me an email with a response. <br> When i tell them it would be much better for them to go directly to the engineering department, they tell me the only thing they can do is to send an email even when they see that nothing is done on my query. It has been over 3 months already and i am still waiting.
