FNB revolving facility is a joke

The revolving facility hasn't been working for over 6 months, They couldn't fix the issue since then which was a simple tax-related issue that was resolved by simply updating the address on the app. How does that work. Once this was fixed the account still didn't work.

While this is happening they continued to add fees and interest. The account has not worked and somehow gained over R1900 worth of debt. I cannot make payments to it, the debit order doesn't go through because the account is "locked" and since November I have received legal threats because of this. They were able to fix it for laterally one day and locked it because of non-payment. So I can't pay it, I can't use it, it's ***** at this point and no one in FNB's call centre wants to assist with this.

I also do not appreciate the attitude I get from the agents when trying to resolve this issue. This is very frustrating and I only dealt with one person who knows what to do, e.g. the one person that fixed it for one day.
