Overdrawn Nedbank Account Glitches

I've banked with Nedbank for less than a year and in the beginning I had no issues I even got my partner to change to Nedbank, and then from December last year I just started having issues with them I addressed the issue with them but I went in circles explaining myself over and over again and they still couldn't assure me that it wouldn't happen again.

So in December 2024 my account was overdrawn by +- R1900 when I queried this I was told that I had drawn R2000 when I had no funds in my account which was incorrect as I transferred money from my savings while in the store to do the cashback, they stuck to their story I was on maternity leave at this time and when the UIF was paid into my account they deducted this money, and I was very skeptical about using my account so I never left money in my current account all the money was in my savings and low and behold a few days later my account was overdrawn by R3000 and this time when I complained they couldn't see that my account was overdrawn by this amount I had to take a screenshot and send it to them, they took a long while to correct this and said it was a glitch and could not assure me that it won't happen again and took no responsibility for it, not mentioning that the person dealing with the complaint was not very helpful and would ignore my emails.

And here I am giving them a review on Hellopeter because again my account is overdrawn now the 3rd time in less than 3 months, it's been 2 weeks and I haven't had any feedback except that the IT department is looking into it, this happened on 01/02/2025 where I transferred R500 from my savings to my current account to make a payment, my balance was then R49.23 and on the 02/02/2025 I logged onto my app and I had a balance of R2049.23 it changed by exactly R2000 and no one had deposited money into my account when I did call the call centre they told me that my account seemed fine and confirmed my balances and stated that my account will not be overdrawn the next day, but guess what it was overdrawn the next day and upon laying the complaint they assign it to the same consultant that dealt with my previous complaint that was not helpful at all and still she's ignoring my emails, I called yesterday to ask for her manager to call me back as a meter of urgency I'm still yet to receive that call.

I'm unable to use my account and receiving smses from them about my account being overdrawn as well as my salary will be paid into that account tomorrow and how do I be at ease with knowing my hard earned money going into this account knowing that they can't manage my account properly and 3 glitches has happened and they have no sense of urgency to solve it.
