Change for bussiness purposes and number of tellers

On a daily basis ABSA-Villiers is not able to provide Businesses with change to use for their customers. We are running a Pharmacy in Villiers and it cost as a lot of man hours to visit ABSA for change and return empty handed. Their excuse is that it took them up to a month to receive their change order. I strongly feel that ABSA is ripping me and other businesses of with their high banking fees, but not providing the service they are suppose to do. Also on about 99% of the month there is only one cashier/teller to help customers resulting in easily an hour spent inside ABSA. This was previously taken up with ABSA numerous times with no improvement.
