Pathetic service

We've been without internet since the 5th of December and Vox and Vumatel have not resolved this issue. I've called multiple times a day and held for over 20 minutes each time only to be told the issue would be escalated. They can't even tell me why I'm without connection. My kids are homeschoolers and I work from home and had to buy mobile data everyday since this problem started. I'm beyond frustrated and their service is simply intolerable.
