Incompetence of MTN

I am extremely disappointed with MTN. No, I am furious at the incompetence of these people!

MTN phoned me to do an upgrade on my 071 number. I told them that I do not have the sim card and they need to deliver me a sim card for tat specific number number. MTN then gave the courier instruction to deliver the sim card, and to phone that specific number to make the delivery appointment. The courier phoned the number that they had in their own hands. Did none of them think this through? Are these people just *********** or are they deliberately targeting me and setting me up for failure? I feel targeted, because the number of people I have spoken to, who actually believe that MTN did not do anything wrong is stacked. If 1 person made a mistake I could oversee it, but more than 6 consultants, customer care supervisor at MTN and the courier makes me believe that they do not want to assist me. The courier tells me to phone MTN to make the change to a new contact number, as they are not allowed to. MTN tells me to phone the courier to make the change. They both verified my Identity and I have given both authorization to make the change. Why does no one on their end have the authority to change it? This brings me to believe that not even MTN trusts its own employees and that non of them are competent. Incompetence in this matter is a fact, as they gave the number that is not in service up as the primary contact number. I have been speaking to numerous people and no one could actually sort out the problem and I'm loosing business and I have spent a lot of money on airtime to try and have this matter sorted out.
