poor customer service - business line

Early in December 2015 my adsl line stopped working. After many phone calls Telkom agent requested that we log a call. It took 6 departments to establish what the problem was. After logging the call technician arrived and said he would come back. I called again, Telkom advised that they will send another technician. 1 month has passed - they now advise that the call was closed and a new call needs to be logged. It has affected my business for more than 30 days now
