useless MTN Part 3

Part 3 of my phone upgarde that went from bad to worse to why do I even bother with MTN, so I finally received the mobile device after 2 weeks of struggling, on the 19th of Nov I called the center to activate my sim and I had to wait fro 24 hrs for it to be active and MTN deactivated my old sim, on the 20th in the evenig I called to find out when the network will be active as my line was still down and I have no working phone, they tried again but actually no one could explain why the network is not on my phone. Today is the 23rd and I still do not have a working line, bear in mind that my number is also used for my work, I have spoken to over 4 people and the reasons I get is that the upgrade was not done well, my number was not ported to MTN and I have been using this network for over 5 years.

I currently have no working line, I cannot make or receive calls. I try to call to cancel and still no answer at all. please call me on ********** urgently.
