An utter joke of an ISP

Ordered a 500/200 line, came and installed, worked well for the first 2 months, then dropped to 100/100. Been calling in for 2 months straight with still no resolution. The only action taken by VOX is general troubleshooting, lots of testing, establishing that there is in fact a fault on the line and that I am not lying and log the ticket request with the infrastructure provider. I'm tired of running around in circles speaking to *********** service providers with ********** customer service. You are better off going on dial up from MWEB then to sit with this nauseating experiences.
