No customer service

I lost a SIM card and requested a new SIM card, which I received and was charged R139 for it. I then requested a SIM swap, which is supposed to take 48 Hours at most, but after more than 2 weeks the SIM card was still not active and no one could tell me why. After numerous calls I had to make to the call centre, I was always given a different story and every call centre agent I spoke to promised to investigate and get back to me but NONE of them ever called back. Every time I called in I had to stay on the line for at least 15 min and in some cases I had to hold for more than 45 min. Since they could not help me with the SIM swap, I then requested a refund for the airtime and the amount I was charged for the SIM card. I was promised that I would receive my refund on Friday 04/03/2016. On Monday I still had not received my refund, and after numerous calls once again I was told that \something\" went wrong with the transfer, but no one can tell what exactly the problem is. I Have never experienced such poor customer service."
