Vumatel and Supersonic no client care...

I reported my Fibre internet line that is off on Wednesday the 30th of June, 6 days later it's still off with no resolution. When I call Supersonic they blame it on Vumatel. I have had to spend extra money buying data and daily follow up calls where I get placed on hold for up to 30 minutes. The service level agreement is 24 to 48 hours... I'm now on day 6... when will this issue be sorted?
