CAPITEC BANK APP INSTALLATION PROBLEM

I was trying to download the New Capitec app from my Samsung a20, as there was a message reminding me to download the new app. since beginning of April 2021 , after downloading the app when its time to install it gave me an error message of trying again later . This morning at 8h30 I went to the Nearest branch which is at 25 Arras and President street Mpumalanga Witbank 1035. I was given tickeck number 014 and I was supposed to be assisted by teller number 09. The Lady had a very bad attitude she told me that she cant do anything she can's assist me I have to deal with my phone or else I change my phone this phone is on android 10 version i bought it last year samsung a20. she didn't bother to even check my profile through my account number or ID no did she try to check with head office to try and get help from the app or IT department. she was so negative and didn't want to help me at all.
