No change available for our customers

I am the operations manager of Cash Crusaders Germiston and I am currently running the store as well. Month end January I spent about 2 hours waiting in a queue by FNB Golden Walk to wait for change for our store and had many customers waiting for me when I got back from the bank.<br> I decided to get my change early this month as to stop my customers to have to wait for me to return during the busy trading period.<br> On the morning of 24/02/16 I walked to the FNB in the Golden walk shopping centre which is on the other side of the centre from where our shop is. I placed my order for change which amounted to R2800, we also arranged a collection time of 12:00. I arrive at the bank at 12:20 and they only have R600's change for me. They also cant tell me when they will be getting the change that we desperately need for our store.I was advised to drive to a different branch to get change from them. Is this the kind of service we can expect from FNB in the future?
