NO SOLUTIONS BUT EXCUSES, 1HR30min on hold!

I give up! 3 weeks ago i recharged with R49 and purchased a 90min voice bundle that is valid for 2 weeks. This week i tried to buy the same bundle and now im told it hasnt been working because my sim card is a data sim? it was a data sim 2 weeks ago and for the past 3years but i have never had issues. I spoke to the consultant , Nonhlanhla from the KZN Branch who was not giving me any solution, told me theres nothing she can do about it, but compromises that would cost me further and not satisfy what I am trying to buy. Eventually I asked to speak to her team leader/manager as I did not want a reference number and hope to be "called back" i needed the matter resolved, she agreed to transfer me and i was left on hold for about an hour and ahalf eventually i ended the call, got a sms with a case number and guess what, STILL NO CALL BACK!'
