I got no help from the number provided by Telkom

I am a Unisa student and spp**** for the Telekom data bundle through Unisa<br> It has been moved than 24 hours and hasn't been activated yet. I called the customer care line on 081180 and they told me to go to a Telkom branch. It doesn't say on the unisa site that we must go to the branch, it says we must call. Why should I call when I won't get the help I need? I'm very disappointed with Telkom and their slow service, I have already paid on the 27th and I have assignments to complete.
