Can't give change!!!

I was at ABSA Ilanga mall to get change for my work. I've been banking with them for more than 12 years. Because it's my personal bank the obvious choice is to go there. When I got the the teller they said they can only help but at a cash charge because the company I work for is not their client. I feel seeing that this is a bank it is ridicules to charge someone for exchanging money for change. Banks make enough money on other bank charges where ABSA is not the cheapest, been doing my research. I feel disappointed in the service, seeing that I had to travel to another bank that was not in the Mall and that I have wasted my time going to MY bank!
