Threatened by MTN staff member in Cedar Square

My wife has a SIM that has not been activated as call centre is inoperative. <br> <br> Staff member took my details and said he will call MTN and call me back. <br> <br> He spelt both the name and surname incorrectly but ignored me completely when I pointed it out. <br> <br> He then seemed unwilling to help. He insisted I try another device even though he could see the SIM was swapped and was told it gets an inactive error code.<br> <br> I requested that he call me back before 17:00 with a progress update. He ignored me again but did give me a clear look of contempt.<br> <br> I asked if that is how MTN treats customers? <br> <br> The staff member then exploded with emotion, accused me of swearing at him (which I didn't do), leaned over the counter, put his face about 10 cm from mine, and repeated several times: \Have a go at me! Have a go at me!"<br> <br> His intent"
