Telkom refuses to fix problem

We reported a line fault at a major client on the 22nd of September, and even gone so far as to help Telkom identify the problem, but they refuse to send a technician! This is what happens when a monopoly is granted and there is no competition. Complacency sets in, and customer service disappears (after all, who else are they going to do business with). The only number you can call to complain is their regular service number, and there is no escalation procedure for complaints!
