Telkom not sticking to installation date

We have moved premises, but will be keeping the same telephone number. Our reference number is ***A. We were assigned the 23rd of January as installation date. The Technician contacted us and set up an appointment however we waited over 2 hours and he did not pitch. After numerous attempts we still do not have our telkom line. I contacted the gentleman which was meant to do the installation and he said that it would be done now on the 4th of February however to date nobody has come and completed the job. The service has been absolutely shocking.
