Pathetic customer service

My land line has been non functional for the past few months, and after reporting it via sms fault line (probably 30 times),also going into the Telkom shop 3 times and holding on for probably an hour on the fault reporting line, numerous times and online fault reporting. Not a single person has ever phoned me or came out to look at my land line. Please tell me what more I can do to get some service delivery? Very pathetic service.
