Missing deposit

I deposited R1000 at the George Branch on the 10th May, and the machine i.e. Cash Machine, only registered R800, the staff member there assisted me, that means R200 is missing from my account. I was told that it would be resolved or I will get feed back within 48 hours. To date, nobody has called me, I have called them at least 8 times. A team leader from JHB also promised to call me back, no call back yet. I logged a complaint today, SMS reads, it will take a further 7 business days to investigate the matter. It's a circus, that's all it is.
