Standard bank blocks my charges and randomly removes my card

I made the decision to move my banking to standard bank because better interest rates on my bond was offered.

I asked if tap to pay was offered in the app so I don't have to carry a card. I was told yes. I signed up for private banking.

Since I got my card, roughly every week my card is removed from the app. I need to reset and readd it. I contacted my banker each time it happened. He passed it off to someone else who insisted on calling me to speak to someone who will tell me to reset my profile. That is the only advice they have, reset the profile. Which has already been done.

I received an email where they are pleased to announce the problem is fixed yet it continues, every week or so my card is removed from the app. I only find this out when I'm at a payment point trying to pay for something. It's incredibly embarrassing.

I've contacted standard bank multiple times about this but no one ever bothers to respond. What am I supposed to do at this stage? Live in ****ing anxiety that my card may or may not be on the app when I need it?

This is in addition to randomly blocking my card for ***** because I used Uber, Google play store and tried to buy something from clicks. What you dumb ****s fail to realize is the payment processor on the other stop also stops me from using their service because standard bank reported my transaction as *****.
