What exactly is the reason for line not working?

On 4 Oct I reported a fault that the line was dead. On 13 Oct is was 'restored'. It was still not working. On the same day I reported a fault again. The next day a technician from Telkom arrived. He tested the line and, in his own words, did not know what was wrong. He said he will come the next day and we arranged a time. The next day he did not come at the arranged time and also did not phone. Two days later I get a call from another technician. He says there is a problem with the underground lines and he reported it. On Wednesday, 14 Oct I get a message that the line has been restored. However, still no service. I tried to report it again online, but received a message that I must call 10210 because there is something wrong with the line. The same line that was reported as 'restored' a few minutes earlier? I phoned to just cancel Telkom only to hear the reason my line is not working is because I didn't pay?! When my account is indeed fully paid, on the website it also shows no outstanding amount. So, what now is the reason the line is dead?
