Rude Call Centre Operators

The first person to call did not even say his name and started asking my personal details to verify my identity. With identify ***** on the rise, I did not feel comfortable to give it. Also, it took him 14 seconds after I had answered the call to say anything. I asked him what the call was about and he said \As I said before...\" which he had not. He then lost his temper and put the phone down. When wanting to lay a complaint at ABSA's complaint line, Daisy answered she was unfriendly from the start and I needed to repeat myself multiple times. I finally said goodbye and put down the phone. AIs this how ABSA treats their customers? "
