Very Bad Service

I have been receiving a very bad service from telkom, I have a contract with telkom and everything was okay till I missed the debit order in June whereby I had to pay manually which I did however was later charged double in August then when I inquire they said is penalties. I then hat to pay manually for the bounced debit order and also the charges. They did not deduct funds in August on the debit order date however they went and deducted later with the charge then it bounced as they were deducting more than the usual installment, they suspended the services and I had to pay manually again with the penalties of the failed debit order that was on their side. I called the contact center last week to verify the amount due for this month and consultants had been giving me a run around and one of them said the will be a deduction on the 05th of November however they never attempted to deduct meaning now they will come and deduct with penalties again. I spoke to a consultant who also gave me his email address to send the statement where Telekom did not attempt to deduct which I did however he also haven't give me feedback for his investigation.
