Telkom Refusing to Close my Account - Still Charging Me

I app**** to cancel my Telkom line and ADSL service on 28 November 2017 (almost 3 months ago). I called Telkom’s call centre in January 2018 and was told that I had a final amount of R308.95 outstanding after which my account would be closed. I paid this amount (although my line has been down since October 2017 following a lightning storm).

On 6 February 2018, I received a further invoice for an amount of R337.17 - again the line is still down and accordingly not in use following the October 2017 lightning storm.

The account has clearly not been closed. I am rather annoyed about Telkom’s inability to complete a simple cancellation request, even though I have done all that is required from my side to finalise the cancellation.
