Bad Customer Service

I have had issues with my internet for over a week now. First of all, when calling to log a fault, I held on for more than 30 at any given time of the day. When I finally managed to get through to log my fault, I was told that a technician will be notified, it is now 5 days later and I am still waiting on a technician to come out. I am paying for services that I am not using. It's a disgrace how customers are being treated by call centre staff. And for them not to be able to give out head office's numbers is atrocious. Which company can not escalate the matter to a higher level. I need this issue resolved as in yesterday!!!
