Telkom have no clue what they doing

i cancelled my policy with telkom in november 2014 due to the fact that they couldnt provide service to my new address (no ports available). in december i receive a call saying i still owe them money on my line, to which i explained that it cant be as i cancelled the month before as they couldnt provide the service. i was promised it would be corrected and i dont owe. In beginning a received yet another call regarding the same matter, but not only did they not correct it, but they added another number to my account that i did not request or have no clue about. the lady i spoke to then Karen - *** assured me that both lines would be corrected and i owe them nothing, only to receive a call today telling me that i still owe them money. they also call on another number which isnt mine, annoying that person too.<br> these people are incompetant and all i want is for my policy to be cancelled and for this ghost number to be removed too. is this too difficult.
