Telkom Staff cancelling line and allocate it to another client

The telephones in the Wupperthal area is constantly off - it only works, if you're lucky, between 9am and 4pm on a daily basis. I've tried to log a call on Wednesday, 1 August 2018, because my fathers line ( ********** ) was off since Saturday, I was informed that the telephone line was cancelled on 4 February 2018. Well only the account holder can log calls or do enquiries, but Telkom cannot confirm who cancelled the line, because my father did not do it. My father had to call 10213 to cancel the 'cancellation' and received reference no ********** 22A . . . They told him, a technician must come out and check if they can activate the line again. Well today when I called the number ********** (a open line), Telkom has allocated it to another client, who's line was off for the pass 2 weeks. Her number is ********** (a prepaid number). Does Telkom's staff know what they do? In the mean time my father received monthly invoices and has paid it.
