I'm tired to follow up with my prescribed account with African bank

I'm tired to follow up with my prescribed account with African bank. I spoke to different people everytime. I was sent emails to say I can login on the African bank app to download my prescription letter but no luck. I went to the Golden Acre Capetown branch and told the consultant to print me my prescription letter only to find out the account is still active. I'm tired really. I was sent a mail that African bank tried to call me and that I must reply to a sms number Hi so that they can call me back, but no call. When I call I speak to other people where I must explain the story from beginning till end. I'm tired. All I want is my prescription letter so I can be done with African bank once and for all.
