Please stop lying about coming to my apartment.

I have never felt as helpless as when dealing with Telkom. I'm stuck in a terrible cycle of apathy and incompetence and I fear that after 6 weeks, 4 visits to the Telkom shop and 2 days of not leaving my home in case a technician comes over, I might never get internet.Twice Telkom has told me that they will come to my apartment between 7:30 and 16:00. Twice I've stared at the gate for an entire day. Twice Telkom smsed me and I immediately ran to the Telkom exchange while my husband stood at our gate. Twice nobody showed up, nobody phoned and when we asked the Telkom shop for the data, we're told that at 17:48 we were smsed and at 17:50 the technician said we were not home and that he phoned. They just lie! Nobody phoned, nobody showed up! Now I'm in the queue again, but what is to stop them from doing it again. I double checked that they have the right address and even printed a map that the Telkom shop could not accept. I follow your rules, I am polite to the shop ladies (it is not their fault), I have no bargaining power because you're a monopoly. So what should I do to pay you money, use your service and stop bothering you?
