Disgusting support, NO INTERNET FOR 7 DAYS AND COUNTING

I am not at all happy with Supersonic. I have now been without fibre for 7 days, line is completely dead. No feedback from Supersonic. I am calling everywhere to get resolution, the only thing they keep telling me is that the issue is escalated. ISP (Internet SERVICE Provider), not in the least, not providing any service whatsoever. Dismal support. No follow up, no pushing to get the issue resolved, expecting the client to phone everyone to find out what is happening. I work in support and would be ashamed if any of my clients experience this. TERRIBLE SERVICE, for a SERVICE PROVIDER....
