Billing Issues, No Service, No help

We had a phone and adsl line installed in January. The technician left no login details, we were told to wait for an sms to say the line has been activated, it never arrived. We never received that sms. Then the calls to Telkom started. After NUMEROUS Calls and weeks of trying, we finally received the correct log in details. Then we received automated calls saying our line was going to be cut because we had not paid. Despite having our physical, postal and e-mail addresses, Telkom never bothered to send a bill. Again, numerous calls to telkom, we received our bill. The bill amount was 4x what it should be. We had been charged for December, the line hadn't even been ordered then, let alone install. We had been charged for January besides not even knowing the line was active. Of course, we were also charged interest. Disputes lodged, declined, lodged again etc., etc. We have never again received a bill. And now, permanent password issues, cannot use the Internet, Telkom says we should be patient. We cannot run our business without internet. Telkom clearly isn't interested in helping us resolve these issues, their only concern is payment for a service they do not provide.
