Annoyed with service

Called the call centre number *** 3 times today as soon as I speak to an agent my call gets cut and no one bothers to call me back as they confirmed my details with me . I have a flexi account which apparently matured on the 26th May 2021 but I only received sms notification yesterday 11th and today 12th July 2021 to contact the call centre number. I need someone to call me back urgently as I DO NOT want to reinvest my monies with ABSA and need this to be paid out. Contact me on my cell number ***.
