No help, clueless and sick staff

I have been trying to activate the Capitec banking app on a new device for quite some time. The sms that's sent from my device doesn't go thru. I've called my network provider who has confirmed there are no issues whatsoever with sending and receiving sms. The issue was not on their end as I received other sms daily. I went all the way to the bank, in ottery Cape Town, spent money to get to their useless branch, wasted my time dealing with a consultant who did not even the fees I will pay when making an online purchase using the card itself. She kept coughing all the while assisting me, which made me nervous. She had to get a pamphlet to read out for herself and me("the client") and what the charge will be, yet she deals with this work every day but don't know the basics! At that point I knew she wud have no clue on how to help or provide any reason why the sms is not going thru to activate their useless app. I returned home, with no solution, no results and to top it off, I am now feeling sick, suddenly my throat is dry and feels sore and I've got a headache out of nowhere. After supper this evening, I researched further, after quite a bit of time, I resolved my own issue. Capitec app doesn't support tablets even if the device is android 10 version. It just doesn't. So u can't even make online purchases, not even using ussd feature because ones internet banking must be made active which I went for in the first place and it an only be utilized if one is using their app. Ridicules. I will be closing my acc very soon. There's no point. I got ended up feeling sick physically and mentally at having to waste money and time and the people who work there getting a salary are not clued up on their products they deal with daily. Do they get paid peanuts?
