Absolute disgusting and shocking service!!!!

absolute shocking service!!! I have been trying since Nov20 to change my debit order date but each month Telkom put through the same debit order on the wrong date and then when it does not go through, they charge me R205.96 every month and suspend my account. I have tried again now to sort this out and had the phone put down on me by the service consultant. In the past I have been put on hold for over 27min with no one getting back to me. HOW HARD CAN IT BE TO GET SOMEONE TO CHANGE THE DATE OF A DEBIT ORDER????? ABSOLUTE TYPICAL EXAMPLE OF THE LACK OF CUSTOMER CARE ONE GETS USED TO BY TELKOM - DISGUSTING!!!!!
