Useless Customer service

Have been fighting for 5 months to get R500 back that was ********ly jnled out of my account to settle another ABSA account that had been closed in August of 2023. They handed me over for non payment of the account - yet I have paperwork stating it was closed in August and even paid the closure fee. I have logged this complaint numerous times and they continue to close the query without resolving the issue. Seems no one bothers to check all the documents I keep sending top them. So annoyed.
