Telkom Fault - months

<p>I have a Telkom Business Landline. My business is a take-away restaurant which receives many orders over this phone line. Frequently the person on the other end of the line cannot hear me - this is damaging my business. I have had a number of telkom technicians come check the fault and report there is nothing wrong. When I ring the helpline and report the fault I cannot even speak to a supervisor - today both Austin and Wesley were unavailable and I am not allowed to speak to the manager Martin. All I want is a contact within Telkom that can manage the fixing of this fault. I am told there is no area manager</p>
