OLD mutual is unable to complete a simple request!!!!

Sometimes, i think listening to the general public helps and one would avoid disappointments such as these. I called OLD Mutual in August 2024 to have them change my debit order dates to the last day of each month and after trying for a long time with the long call centre queues got someone who confirmed that my request to change my debit order for both my policies with them has been completed. I kept being debited on the 25 for the remaining months until last month when they did not get funds in my account. I want to warn people to avoid this business if they can and rather look for competitors in the same field. I want the call recording for the 19/08/2024 sent to me via email. I want to lodge a formal complaint against this company!
