No response from all internal complaints channels. Terrible Service!

I am really disappointed in the terrible service I am receiving from Absa. I have my bond and vehicle finance with them. I had my current account for many years and closed it. I will definitely not be taking any other accounts with them in the future. I closed my current account in May 2025 after many years. I made an online purchase with my Absa Card in April 2025. I got a refund from the online store and it went into the closed current account and never bounced back. I sent the proof of payments but still no response. I was in the branch 3 times but they could not assist. I was told to send an email to ***. its been over a week and still no response. I even escalated to actionline and the ceo office and they cant even respond? I am always reminded why I should never do any kind of business with Absa. I guess this time will be the last.
