Ruthless to financially distressed clients

I've asked ABSA for a paid up letter for my account under debt review on 28 Nov and by 17 Dec, I have not received it. The problem is that ABSA is ruthless when it comes to financially distressed clients, they don't care and will cancel debt review arrangements without blinking, in 1 second! But when it is their turn to provide a service, you just don't matter. I WILL NEVER DEAL WITH THEM AGAIN IF I DON'T HAVE TO!!!!! Unfortunately for me, I have 2 more accounts to pay up with ABSA, and they're milking me on interest and the period! It is actually appalling and horrific if you review it objectively from a South African borrower perspective.
