Debit Order Dispute

It is with a great deal of dissatisfaction and disappointment for me to be writing this, I have been with telkom for over 3 and almost 4 years now on a mobile contract and when I first realized that a debit order of 'more' than what I have signed for went off, I called in and a Telkom agent explained why i was paying more which i understood after they shared a light with me.

I then asked for them to stop that from happening and just stick to the amount of R299 Which was what we agreed upon and stop all the other cost from ever incurring, they agreed but now the same thing is still happening and now I am angry and very upset with about this,

Each time I call in for the same thing and someone always promises to stop this but to my surprise, it never stops....

Telkom Sucks and do not deserve our support as they continue to treat its customers like ****.
