highly dissapointed

last week Wednesday on 17 of October my number was out of network and on the 18 of October 2018 I call the Foschini one2one call center and they told me my number has been deactivated. so I didn't know why my number has been deactivated because I had paid my account at Foschini and I was not even owing them any sent. And I had closed my account and cancelled everything. So when I call the center they told me to go buy a new sim and Rica it and I must not put that Rica sim card on the phone before they call me. So I did that, and even today I'm stilling waiting for them, When I call them today and ask them how far with my they changing my number to prepaid because since they told me MTN has not respond to their email and MTN has a backlog. But what surprises me when I call MTN they told me there's nothing they can do because my number it's still under Foschini group. And I need my number and I have been using it for the very long time before I even had an account at Foschini and its linked to everything that I have. I will really appreciate if you can help me since I told them I'm going to report them this morning they told me I must go ahead if that pleases me. I am so frustrated they way they have treated me.Since I was a loyal customer at Foschini group. This my consumer right,
