Unprofessional, unorganised, TERRIBLE customer service

Firstly, when Vox came to install my internet line, they drilled a hole through a water pipe, dropped and broke my double volume bookshelf, and broke a light fitting. But that's not why I'm complaining... I am now on day 6 with no internet. My 4 month old router just suddenly stopped working. I spent an hour and almost R100 airtime on the phone with them trying to fix it - no luck. Was told then that a technician onsite would come out and fix it within 72 hours, and that I was marked as urgent since I work from home and really need my connection. Guess what - it's been over 144 hours and still no technician. No contact. I have called every day, twice a day, only to be told they will contact me with a time to come do the fix - which hasn't happened, of course. On the phone NO ONE knows what the technicians are doing, I was told that being marked as urgent means nothing, as they go in order of when they got the requests. So I was **** to then, basically. Don't the technicians have a schedule where they can see how many people they need to see each day? They can't give me a time? This is absolutely unacceptable, unprofessional and ridiculous. And I bet I'm still going to have to pay for all these days of no service??
