5 weeks and still not helped

5 weeks ago telkom put up a new exchange in our street. When testing our line they got the wrong number and just cut the line. Since then I have had 2 technicians at my house both saying its not their job to repair the line they will escalate the problem. I have also phoned the call centre and after 20 min of holding I finally reach someone and they to tel me it will be escalated. I don't even get messages from telkom to inform me when my problem would be fixed!
