Telkom is bad for your heart!

In December 2019 my invoice contained an item titled event Billing Usage amounting to R3344,40. I went to a Telkom store to query the invoice, the assistant could not assist and advised that I contact their billing department. On 15 January 2020, I logged to my Telkom online profile and lodged a dispute, this was closed with any feedback. I called the billing department, I can't remember the date of the call, the lady that I spoke to confirmed she has logged a query on the issue I raised and I will receive an SMS confirming details of the query. The said SMS never came. They have been attempted debiting my bank account and I have been reversing the dubious charges. Sadly this has now become a costly administrative burden on my part in that I have to call the bank to have the charges removed, and every time the charges are removed I have to pay an admin fee to the bank. On 29 April 2020, I submitted yet another dispute and followed it up with a query logged on their website. To date I have not had the pleasure of any kind of contact from Telkom on my issue, all I receive are inflated invoices at the end of the month. It is now the 6th month of the year and I am still chasing the same issue, no seems to care.
