Telkom has no regard for its clients

This is the third or fourth time I write about Telkom and its abysmal performance together with an uncaring attitude toward clients. Telkom continues to pursue me concerning an account that was cancelled in good standing but they have now created an outstanding balance by continuing to bill me, and this continues to grow. Their cancellation reference is ********** 6 for 1 December 2016, which they say was never confirmed because I did not answer my cellphone when they called to confirm it. I was never warned about this call, and I was unavailable at the time of the call in the Western Cape. Telkom have never given proof that they actually called me. The fact that I went into the Telkom Shop Menlyn on 1 December 2016 to personally cancel the contract is intention enough on my part. I have had a lawyer on this, to no avail. Telkom continues to pursue me, regardless of what has been said and regardless of evidence that I did in fact cancel the contract (above reference refers).
