Poor customer service from customer service manager

Went to the bank 28.03 to close my account as advised telephonically by one of the banks agents that called me in Feb 2024 wanting to know when will I be making a deposit as my cheque account was overdrawn. Its been over 3 months I haven't used the account due to personal reasons,However interests were billed on the account.Pretoria Noord ABSA customer service manager couldn't explain the sudden R1089.00 that I needed to pay to have the account closed. She mentioned that I must go to Menlyn where I opened my account and that maybe they will write it off but they can't help. This is after I have been to a Teller that couldn't tell me why I needed to pay R1089 to have the account closed after I have paid R700 in Feb 2024. The agent that called in Feb advised of some R500+ overdue before the R100 + R600 was paid. When I asked the CS Manager to freeze the account whilst she looked into the matter, she said she will investigate but unfortunately the account will continue to accumulate charges. She just didn't have answers. Couldn't speak with authority. Was not interested to look further into the details and understand the urgency to assist as I made her aware that I work in retail and hardly finds time to visit the bank and today was the chance I got. Which took me "about" 2 hours in the bank and still left the matter unresolved. How is a manager failing as a custodian of an institution to show interest in running the operations and ensuring sustainability and eliminating such essays as this by taking the time to understand before they speak and to always remember to make a difference? I'm disappointed and this confirms that I'm making a good choice to close this account as I was a bit unsure but after today. I really would like to have my account please closed.
