Capitec bank bad service Mall of Africa

On the 20th August I could not have access to my banking app un-installed it and installed it again the following day same thing even yesterday. Today I went to Mall of Africa to the branch to report it but could not get help the lady who was helping me even asked me to reset my phone I did that, I was there 13 :15 and at 13:45 the lady also couldn't help me for 30 minutes. She told me I must keep on trying to get access so I tell her I have been trying since Tuesday she says there is nothing she can do. I asked for the Manager they say he is on lunch he will be back 14:45 that time I'm also on duty I went on my lunch then they say I must come back at 15:00.My problem is if the bank can't help me who will help me, then it means there is no need for me to bank there if I can't get help. So I'm even going to close the account cause it's my pay day I need to use the app but I can't
