Land Line Installation

Good Day, a owner at one of their industrial companies, went and bough a installation of a land line at their home in OCTOBER 2014 and still waiting for the installation. It has been paid and mailed to Telkom. We called last time and they said they are waiting for a cable, and when we searched the ref no. It says it does no exist???? If this is the service he is getting from Telkom he will move all of his internet connections to a wireless supplier. No one can help him at Telkom Buss as this is for his home use to connect to the work. We have the proof of payment, all the details given as well as proof it has been mailed. its almost half a year and still nothing from Telkom. If you call their call centers you will wait almost 40 minutes and then they will hangup on your call
