Rude consultants ?

I went to the Branch in Kroon street Roodeport today. When I got there, the door was closed with no notice. One consultant who did not have a name tag came out of the branch and closed the door again. and so I asked her what was happening since i needed assistance inside . She rudely looked at me and said "I don't know " then walked away. It's very frustrating when you need assistance from a bank which holds an account with you but get treated like you are not a valued customer. If they were having technical problems then she should have said so instead of rudely saying "I Dont Know". There are operating hours on the door and I went during operating hours. If for any reason you cannot open during the times specified, please ask your consultants to at least advice on the reasons clients can't get assistance.
