Reverse rejection fees

I posted this message on the 20th of Aug in response to a message from Telkom and no one has responded so I am sending the message again. I need to speak to someone face to face in order to resolve this issue, can I get details of one of your office in Johannesburg so I can go speak to someone there. I have once again reversed the debit order of R814 because I do not think I should pay this money. See message below:

While I wait for someone to give me a call, according to my records, this is the series of events: 1. I informed Telkom in August about my new banking details and they were not updated 2. I informed Telkom again in September and the banking details were still not updated, I phoned, e-mailed and even tweeted and the details were still not updated. 3. Telkom continued debiting the incorrect account and once I noticed I would do an EFT. 4. I was charged R200.94 for rejection fees (why??), this amount was carried through to the following months. 5. My banking details were updated at the end of Dec, but now been but the subscription & once-off charges were carried forward, instead of being billed R149, I was billed R498.94, Invoice date 01 Dec 2017 6. Invoice date: 01 Jan 2018, I was billed R200.94 rejection fee AGAIN!!(why? it's not my fault that your people did not update my banking details). I should have been billed R149. Amount outstanding R498.94 7. I then decided to pay the account before the debit order date, I started making payment on the 15th of every month, started on the 15th of Jan 2018. 8. So at the end of Jan, the one rejection fee was reversed but not the second! why? so this amount was carried forward from hereon and this has created problems!! 9. Because I was paying the account on the 15th of every month, I didn't see why my account was debited on the 15th of every month so I started reversing all debit orders. 10. So now Telkom is charging me for reversing the debit orders which should not have been going through my account in the first place!!! 11. So all of this would not been happening if your people were doing their jobs, if my banking details were updated last August, then this mess would not have been created. 12. My account has been suspended but I am still making payment on the 15th of every month, the outstanding amount is at R900+, I refuse to pay for this because I should not have been charged in the first place. 13. Can I get an appointment with someone so we can resolve this in person!!
