Bad client service

Today I went to mokopane mall branch just to get a stamp because I'm newly employed. When i got there the door was not closed. I got inside and found two ladies by the hello point. I told them i don't need anything from the system, just a bank stamp. They said no we are closed.One of them said they need to confirm my banking details. I asked them to use the sst to confirm that. With an attitude, they both shouted at me and said no we are closed. Im switching to another bank.
