Shame on Standard bank

I've never experienced such level of incompetence from any organization in my entire being. I have financed my vehicle through standard bank and have been paying my account and it has been up to date until one morning a Lesego Hlongwane decided to wake up and say there's an outstanding amount of a mere R1550 which should be urgently settled. I then put together all my monthly statements that I received from them and sent it back to them proving that my account is up to date but I have been waiting for a Lizeka Gogotya or something like that and a Shawn Pillay to provide feedback for over a month now. None of them provides feedback unless I follow up. I'm following up with them as if they're my clients when it's the other way. Shame on you standard bank for harbouring such an *********** bunch.
