One year later my account has not been cancelled

<p>Good Day Telkom</p> <p> </p> <p>I have written numerous of times. Thankfully this is on the internet and not a waste of paper. I requested that my line be cancelled as the account had come to the end of its 24 months. This was in November 2015. My new device was ****** in July of 2016. When I went to Telkom to do a sim swap and get my old number back they said there was an outstanding amount on the contract. I asked for which number becuase there should only be one number on the contract as the other two numbers should have been cancelled. The number that came up was a number that for the last year was on prepaid. No one can tell me why the two number I requested to have cancelled have not been cancelled. I have sent the relevant documentation to Telkom 600 times over and still nothing has been done! The account has apparently been sent to collections and written off and is waiting to be paid when there should not be anything outstanding! I am very unhappy! </p> <p> </p> <p>Please solve it!!! </p>
