Denies app is not working

The Absa crashed when logging in, even before getting to the password stage since the last update. When phoning the internet banking department, they denied that there was any problem whatsoever despite the plenty reviews on app store mentioning the same problem. Danelle, who I spoke to, blatantly said they don't read the feedback on the app store. Very inconvenient at month end. Also, probably the most ******** 'technical support' I've contacted in a long time.
