Telkom service non-existant

Telkom fault number 15CWK250416 logged Monday and by Friday still no response from Telkom. Telkom will still expect me to pay the full monthly line rental fee even though I can't use the line. Doesn't Telkom have service level agreements where they agree to fix your line in a reasonable time like 48 hours? Clearly not. They would if I could go to another company for a telephone line. No wonder their fixed line customers are declining every month.
