If you want forex today forget going to Standard Bank Cresta branch

I'm leaving to go abroad in a few days and have been watching the exchange rate keenly with the current political situation. I went today to get forex and was told the following: Only ONE teller and ONE booth for foreign exchange. If the teller is busy - there's a long wait (some customers take an hour or more to conduct their business. But it gets worse - if the ONE teller is on lunch and you go when its your lunch time - forget it. nothing happening!! Or if he's ill or away you have to GO SOMEWHERE ELSE. The forex booth is closed!!! I tried complaining to the senior staff and they said that this is a daily complaint and they are unable to assist me unfortunately. Cresta is the only forex branch in Mogale City area and they only have ONE teller. After waiting 2 to 3 hours and to be told another 45 minutes is unacceptable. I am not blaming the teller - he is only human and I'm sure doing the best he can. It was suggested I go to Rosebank or Sandton branches (kms away if I want some service. This is absurd. I also ask who is paying for my time, parking and petrol? Certainly not Standard Bank. I am really angry and frustrated. I have been a customer since 1973 and find the lack of service generally unacceptable. Long waits for simple things like renewing a credit card, seeing a consultant or trying to get forex. In a country where there is so much unemployment - how about training and employing more people? Perhaps the message you are sending me is GO to another bank or financial institution where get I can get better service? I see that this business isn't claimed on Hellopeter -so am I surprised? Is my complaint important? Perhaps not.
