Capitec funeral policy and poor service

I have been banking with capitec for more than 10 years, so ended taking their funeral cover. I wouldn't advise anyone to take it, I have not claimed from them but the fact that I wend to amend my policy and they don't have it in system but it's on my app it's really surprising, what kind of bank is that. So they printed old documents and the agent said I must not worry as long it's on my app, when I told her I need to amend it how do I go as they don't have in system she took the old policy made changes with a pen 🤔and I asked so a covered member was covered long but now it's showing today's date, she said it's not a problem. I am stressed if anything happens within 6 months I doubt if they will assist meanwhile they telling me not to worry. I really need to leave this bank and look for better bank. What a waste of trusting them whole 13 years nxa
