No client service!

We relocated to the south coast kzn, called in October to do a line relocation. We were informed that the line will be installed the first week in December. We still do not have a line or internet and have had no help from telkom. They are either off line or just escalate the issue to the back office which deals with these issues. We cannot talk to the back office or have any contact with them and receive no feed back from them what so ever, not sure they even have a back office? We have been told supervisors will be in contact but have yet to get a call, message or e mail. If this is how their clients are served then unfortunately we will be cancelling our telkom line and will move to a mobile network!
