card limits can not be changed on the Capitec App

I am unable to changed the card limits on the Capitec mobile app. The limits are "read only" and can not be changed. I've been instructed to change the limits using Capitec online banking (i.e. laptop browser) instead. I can't do this either since I am unable to log into the online banking service i.e. the service is currently unavailable. The "customer support" solution is to email me a Docusign document with the limit change and approve the limit change online using Docusign. This is far from ideal or convenient and has wasted hours of my time this morning. I suppose I should be grateful that there is a solution at all.
