Continuous bad service

I’m so disappointed with Nedbank since from the 23 February 2023 I’ve been begging them to change my debit date and spoke to several consultants with no help Neo the lady,Vuyani,Minkateko,Thobile,Nthabiseng I’ve spoken to a lot of people.as a result my credit cards were in errears which I decided to make payments early August on both of them to keep them up to date as according to the discussion I had with Neo who had already promised me that my debit date was already changed and she removed the debit order for August so I can go make the payment that I was in arrears for after that it will be back to normal debiting on the last day of the month,as mentioned I went and made payments early August and I was finally relieved that now I’m up to date to my surprise I got a call on the week of the 25th from Vuyani telling me my account is in errears I was confused cos I knew I made payments I’m up to date now only for him to tell me my debit date was not changed,what must I say Or how must I beg Nedbank to change my debit date?????problem number 2 I rushed to go and deposit the money after I was told my Acc was in errears on the 31 August 2023 deposited R500 which failed and the atm returned my card but never returned the cash,the security told me to relax and call the number provided for such queries indeed the lady(Indian or white) assisted me and assured me it will be sorted I must relax ,I have her all the information she needed including atm number and all my details,I received an sms with a ref number and told me after 3 days the cash should be deposited back to my account,a few days later I received an sms saying my ref number was declined don’t know on what reasons ,I called and spoke to Minkateko asking what’s going on she was unable to help as she said she also doesn’t understand what happened but she had escalated the case to her supervisor who will call me till today nobody is getting back to me,I’m honestly sick and tired of the sick service I keep receiving with this bank.

I want my debit date changed immediately and my money Bach and I won’t be liable for anymore of the extra charges as this is all your negligence or else I’m taking this matter to the ombudsman
