No internet for over a week!

I have had no internet connection for more than a week now and after several calls with my ISP the issue has not been resolved. They came to the conclusion that is was a Vumatel issue and have been logging tickets to the Vumatel team but to no avail! I just keep getting told that the issue is being escalated and I will be contacted by Vumatel. I still have not been contacted by Vumatel and I can't continue to sit and wait patiently for a technician to come out and sort out the issue while I keep spending MORE money on data as I work from home. I trust this will be sorted out as a matter of urgency!!!
