Disrespectful agents and inconsistent debit amounts

Dealing with unprofessional call centre agents who have little respect, who explain that Telkom missed a debit order, and even after making a cash payment after a mistake from Telkom, expect me to pay for the missed debit order. This is the third issue this year I have with Telkom, after my account has had ********** activity on it due to Telkom and not even being informed by Telkom about the ********** activity. The contract will be cancelled and taken up with the CPA.
