Pathetic service

I requested a Static IP address for work purposes and was sent one via email. I rebooted my router but the address didn't change. On 23rd January I called for assistance and since then I have had no internet at all. I have made numerous calls for assistance and all I get told a technician will be in contact and when I called again today I was told the technicians don't work weekends. I need internet in order to work. We have been without internet and can't work or even watch TV. Nobody gets back to you. My WiFi will connect but no data connection. The gentleman that helped me last night said the problem is with the router and a technician will need to come out. This keeps getting escalated but nobody contacts me. Are they prepared to explain to my boss why I can't work. I'm already paying almost R1000 a month and this is the service I get. PATHETIC
