Cut my companies new lines without any notice

I ordered new lines for our company. It was installed and a technician by the name Wayne came to connect all the lines. I told him that I have a guy that helps me with any telkom issues for the last 3 years. I forced me to put it on paper that I have my own support person. MY lines were working great for 2 weeks and then suddenly on the 12th of June we were cut off. Wayne never send confirmation through to the departments to load the lines on our companies bill. So now I have no proof that I had the lines for two weeks and Bella Nkondo keep promising me that she will get it sorted. After a week of no feedback from here I started calling various people. No one can help me because they cannot pick the lines up under our company. Most of my anger and frustration is the lack of feedback. We are stockbrokers and are going through a crisis. Loosing business and in the end clients.
