SLA well exceeded

I have logged a fault with my ISP regarding no internet connection. I have been told that the matter has been assigned to a technician and one will be dispatched as soon as one becomes available, no ETA can be provided. My frustration is that this is now a week later and have not had any joy in getting the problem resolved. My ISP keeps telling they doing all that they can and they are waiting for Openserve to send out a technician. I am getting nowhere slowly with my ISP as well as Telkom as they both seem to have their stories in check and yet I am the one experiencing the inconvenience. I can't even get a manager's name to escalate this matter. Doubt I will even get this issue resolved today after complaining on this forum.
