Telkom is ***********!

I am quite frankly fed up with telkom's utter incompetence in regards to my cell phone account. On the 25th of March 2021 the telkom debit order did deduct from my bank account, now suddenly I am in arrears again and my phone has been blocked due to collections, that is concrete proof that telkom did NOT DEDUCT THE CORRECT AMOUNT via debit order from my bank account, now suddenly I am in arrears with R537.00 . Why on earth can't you just deduct the correct amount from the start, there was more that enough money in my account!? You are *********** and now I the customer has to suffer because You (Telkom) do not posses the ability to manage an account. At this stage I feel like canceling my contract, but I promise you this, after this contract is finished I will go to another Cell phone provider because Telkom is the worst of the worst!!!! I wish I could give you a rating with a minus here!
