Telkom debit dispute-Misleading information

I'm having a bad experience with the Telkom account. I made a manual payment on the 28 of April and they added a penalty to my account of R222 even though my account was up to date. I phoned customer service to query this on the 1st of July after noticing that they debited extra and I was told that I needed to make a payment 10 days before the debit order date. This information was not communicated to me when I was taking up the contract and the agent(Chelsea Beukes) was not even willing to escalate my matter. Ever since taking up this contract, I have been having issues with Telkom and their unending chargers and they are also not able to stick to their debit order dates. Initially, I was told that the debit order date would be on the 1st of each month and recently they changed that and said it on the last day of the month each time I called customer service to get clarity on these extra charges I always get agents that are not willing to assist. sometimes I'm being told that the matter will be escalated to account but I do not hear any feedback or resolution. At first, they gave me an open contract even though we agreed on top-up. I only realized it a few months later when my bill was very huge and even on that matter I didn't get help, they only advised me to set the limit even though I didn't agree to open a contract. It has been not very pleasant to work with Telkom. Its like they are misleading us so that they can milk us at the end of the month.
