Continuous bad service

<p>Good day,</p> <p>I would like to lay a complaint regarding service rendered to me at MTN Wonderpark.</p> <p>I upgraded and did a sim swop on 13 May 2016, at the above mentioned MTN shop. On 16 May 2016, I received a sms, stating that I should return to MTN Wonderpark because the sim issued to me was faulty. I returned to the shop on 19 May 2016, the lady who assisted me previously had already left for thd day, and consequently I was assisted by another lady, she was not aware of the problem. She couldn't assist me, and told me that she could not replace the faulty sim, because they had no sim cards in stock. She took my details and said that the lady who assisted me previously will call me back when they have new sim cards in stock, as yet, that has not happened. Which is now 4 weeks outstanding.</p> <p>I have a problem with a MTN shop not having sim cards in stock, and complaints of customers being ignored</p>
