No connectivity because of huge error on Vumatel's side

Hi this is the second time this situation has happened. My line went down yesterday. Vumatel technicians came through to check the issue. A network operator on the phone with them said she couldn't pick up my line, said the line looked like it was cancelled and then instructed them to put in another box. This was unnecessary since the line wasn't cancelled. This was an error on their side. The issue could have been easily fixed. Now since yesterday I've had no active line at all and Vumatel is failing to respond to my ISP. As I indicated, this happened in January as well. The technicians and network operator who were involved in this issue in particular should be held to account
