Lack of Training and client confidentiality not respected

I am not happy with the service I got from ABSA Vanderbijlpark branch. I sat with the consultant for +/-20mins to unblock my card and install the banking app on my phone and I still left the branch without the banking app of which she struggled to install it for 10/15mins and still failed to install it. The consultant was also discussing another clients private issue with her colleague while assisting me. I am really disappointed that I sacrificed by time from work to get help but I received the worst service and that as soon as we leave we get discussed... I will definitely move my salary else where
