Bad attitude on queries

This is to complain about the bad attitude of a Mr Neels Barnard, after phoning Telkom sales department about a query on the installation of my fixed telephone line. I arranged for the line to be installed on the 8th October, received a message on the morning of the installation that the technician has been dispatched at 7:35 am, at 11:30 am, the technician wan't there yet. Phoning the sales department, they gave me Mr Barnard's telephone number, he blatantly just told be he won't deal with customers directly and hanged up the phone. This is really in bad taste, and terrible customer service. After that, I still wasn't able to find out when he would be there, I have to stay at home the whole day, just waiting......
