Shocking service from Telkom!!!

We are on a VOIP system at our office. Our phones have not worked properly since September. The latest fault we logged is 368CWK***5. After making sure that a technician came to site (he did not even call to arrange), he spoke to my service provider (because he has much more technical knowledge than I do about what is wrong) and said he was going to check something and then never came back. I called Monday or yesterday (called so many times I cannot remember) and was told the fault is still open and a new technician will be sent out. I called today and was told the fault was cleared on the 18th. How can the fault be marked cleared but our phones still do not work??! I have re-logged the fault 132CWK231215 ( I think this is the 6th time now) and they have made more notes that a technician needs to come to site and fix whatever is wrong. Will it actually be fixed this time?? And when?? Four months with phones that don't work properly and no one willing to put in a little bit of extra effort and actually sort it out?! Not to mention the hours I have spent on hold waiting for the call center to answer!!<br> <br> How do we get this sorted? We cannot carry on like this!!
