Please please improve your service and schedule your system updates at a more suitable time. PLEASE!!

Capitec please for the sake of god can you please improve your service with regards to online banking and access to account via the app. Today is now the 6 or 7th time in less than 3 weeks that the app is down for maintenance or just not loading to access account/s. When addressing the matter with the branch I am informed it is due to system updates. My question is why must the updates always be done in peak hour or during the busiest time of the day. Why can it not be done during the night from 00:00 onwards?? I am seriously considering closing my account with you Capitec and moving back to a bank that I get charged more for fees but reliability is at least 100% where I am guaranteed 100% uptime on my internet/app banking. Your service sucks and any person wanting to sign up for your services should seriously get their brains tested.
