Fault reported 3weeks ago- no feedback

A fault was logged on the 11 august for a deadline. I recieved no feedback. I contacted them via twitter a week after, they claim the issue was escalated, I phoned the call centre a few days later to follow up only to be told that the escalation no. I was given was an old one from 2010 therefore no one was dealing with my query. I have contacted them again this week and they said they can fix the issue by month end- now this is not the service i pay for from telkom. Thier techs backlog in work is not my problem and they should not expect thier paying customers to take on their issues. I refuse to wait any longer for feedback from them, in the 3 weeks the only feedback i get is when i contact them and they make no effort to call or sms me updates. We need a tech out now to fix this issue, we cannot wait until before month end. And I demand a credit for the weeks I have had no phone for. I cannot pay rental for something that doesnt work for weeks. Telkom Service is the worst and expecting customers to deal with no service because of their inability to manage their employees work loads in ridiculous.
