Vumatel poor customer service and no delivery

Our fibre line was tested by Vumatel and found to be working. Now we don't have any connectivity and we can't be productive because Vumatel has not handed the line to Vox, this is poor service for days now. This is unfair to us the consumers and it's poor service delivery. Can someone at Vumatel take responsibility and resolve the issue. I have made several calls to Vox about this.
