**** of a service

I ported from my network to Cell C. Firstly I lost my number then the number that I had ended up saying sim card invalid. Now I do not have a number. When I call cell c they told me to buy yet another sim card and rica it and call them. When I do that I am told the sim is not Rica'dhy am I being sent from pillar to post for my number that I lost from porting to them. Cell C really sucks, I just want my number back so that I can port back to my network.
