Poor level of Service

I have had a company deducting money from my Absa bank account after my file was suspended with the company and so in September 2022 I went to the nearest Absa branch to dispute this transaction and the lady at the branch told me that they couldn't dispute debi check transactions. She assisted me by calling their Head Office or Call center and the lady on the phone took me through my app step by step as to how I could get the money to be reversed into my account and it was successfully reversed back into my account. In October I noticed that the same company deducted the same amount it did in the previous month and so I did everything the lady on the phone advised me to do back in September but this didn't work so I went to the branch again and asked them to call the call center/Head Office and they did but this time around the person I spoke to said it was impossible for them to reverse a debi check into my account and so I asked how it was possible the previous month and they told me they don't know. I was referred to the ***** and debi check department, there was a lady who was or is in charge of this case she asked for the transaction details and I sent them to her via email. This morning I received an email from her telling me that according to her investigation I never disputed the debi check on app nor did I dispute it at the bank. I am confused as to how that is possible because I was at the branch and I was assisted by the consultant which went through the steps on my app. I am really disappointed with the level of service which Absa has given me. It just goes to say that their investigation was inaccurate if there was an investigation in the first place. I have been with Absa for longer than I can remember but I have never received such poor service
