PATHETIC fibre signal and ZERO customer care

I recently signed up for Fibre, and received reasonable service for the first week. The second week, my Fibre signal is down to 1 Mbps download and I'm not even able to access my server, nevermind stream movies. Various emails to their "customer care" with screenshots open a service request, only to close them again without even bothering to fix the problem. For a week, I've not been able to work. When I called their customer care line, they didn't even see a service request for me on there! This is absolutely ridiculous!
