Inconsistent and unhelpful service delivery 🙄 😒

The worst customer service ever. I called the call center for assistance with updating my banking details as the system was giving me hiccups when withdrawing from the 2pot system. Application went through successfully. I called to advise that the banking details were loaded incorrectly, I was then asked to send my documents via email which I did. When I called to confirm I was told I didn't need to send as they would verify with my employer. I relaxed because I was put at ease. To my surprise the documents were not received or attached I called a few days later to be told to resend which I then sent again. I spoke to a team leader which guaranteed that she would call me for feedback on Monday. I sent her an email to find out how far she was with the feedback with no luck, the only response I got from her was that she will let me know once she has feedback and I should wait for the 20 days period. Which I don't have an issue with. My problem is that should the payout go to the incorrectly bank account when application gets finalized which I would be doomed. The team that assisted had no sense of empathy about the whole situation. The leader did not honor her word. I'm honorstly disappointed by the service provided.
