Loss of Business due to faulty Telkom Lines

I am a General Practitioner in Garsfontein renting 2 business lines and 1 faxline from Telkom at R235.97 per month per line. A week ago our lines became so noisy that no one can hear anything when calling us.<br> We immediately logged the problem and was assured a technician will be send within two hours. It is a week later and despite numerous calls to Telkom (We've got all the ref nrs) still no one came. I send my receptionist in to the local Telkom shop today and she was told the fault was never logged!! They promised to send a technician today, but no-one came.<br> I do not know what more to do. I'm losing out on at least 15 patients per day.<br>
