Telkom not activating my new sim card for 2 weeks now

I bought a cellphone on contract online at Telkom on 17 Jan 2019. A few days later a pre payment amount of R399 was debited on my account by Telkom. Then on 28 Jan 2019 the phone was delivered to me. I was told the sim card will be activated between 24 -72 hours from time of delivery. To this day 08 Feb 2019 (2 weeks after) my sim card has not been activated. Since the 72 hours passed I have been calling Telkom everyday (my brother and my sister have also been calling on my behalf). Every time I call i'm told the matter has been escalated and I should wait 24 -48 hours, sometimes I'm asked to call a different number and they keep sending me back and forth to different lines. All the time i'm referred to Sales department and even they can't help me. I was given a case number ********** 9. Then to my surprise yesterday I receive an sms saying my case has been resolved yet I still don't have a working sim card, I don't even know what my sim number is because the sim has not been activated. My frustration with Telkom has reached a boiling point because i'm supposed to be having a phone with airtime and data as per the contract package and i have already paid this R399 yet I find my self running at a loss because I still have to buy prepaid data and airtime using my old MTN sim card. Yesterday I called asking that they provide me with a courier number so that I send that damn phone back and they wouldn't give me. I have asked to speak to team leaders and people incharge when I call but there is still no change, to there is an individual in this company who would like and say the case has been resolved when it hasn't is beyond my comprehension. I am a new client at Telkom and already their incompetence has made me want to remain with my current service provider and I want to expose them and my fear is that come month end when their instalment is due they will charge me when I've already lost a lot already.
