MWEB worst service in South Africa

Worst client service from mweb..... I will give them a rating off minus 10 I ordered a MTN LTE sim card about two weeks ago and up to today the card is still not active yet I spend hours on the phone try to sort it out but still nothing happens I also did send about 50 emails regarding my problem but until today its not sorted. I even ask for the CEO telephone number but all the staff members working for Mweb cannot help me.... Some provide me with wrong number and some don't even know where her office is situated.

Can someone just tell me how can I sort out this problem or must just cancel it and go somewhere else
