Telkom Bad Customer Service

I bought R149 LTE data bundles x2 from telkom and they do not work on my phone. I have tried calling their customer line numerous times to speak to an agent who can assist in solving my problem and all I keep getting is sms messages requesting me to buy more of their services. Can someone please Call me back to explain what on earth I have been buying that's useless to me. I need the data to work is do my job.
