No communication from Telkom

I ordered an adsl line, with one extra line, modem and lit TV box through a Telkom LTE agent, who was brilliant. The order went off fine. Then a telkom technician came out on 25 June to install. He checked that my existing adsl line was connected, said that is all he was told to do and left. Telkom's 10213 call center confirmed on the 26th of June that he should have installed a second line and modem as well. Another booking was made for the 28th of June. No one pitched. What we could ascertain on that day is that the order was closed as "done" by the technician who came out on the 25th. I am accordingly receiving smses saying that I'm paying for the line and service now as the order is completed. Since the 28th I've not been able to get through to Telkom when their system is up. The call centre agents say the system is up sometimes, but it hasn't been up one when I phoned. Everytime I hold on for 10 minutes plus, just to be told the system is off. I cannot ascertain why a technician hasn't come out, or if and why the order is closed. Nothing. But I'm paying for a service
