No Assistance

I've been struggling for months with FNB. They have messed up my personal loan account, and no one seems to be able to fix it. I have gone to the Tyger Valley and Canal Walk branch, both have told me to call in. I called in then they tell me to email. I emailed then no one replies. I called in again several times again and my account has still not been fixed, and they can't seem to figure out why the debit order is not going off. One consultant even told me that the issue is on my side because there's no funds (even though I just got paid). I called again almost two months ago asking that a manager contact me, and I have still not received any call. They also don't want to tell me how to get my call recordings, and the consultants on the app also don't want to provide me with the manager/ team leaders email address.
