Terrible customer service & HIGH RISK ignorance by FNB

Recently received a new debit card as my old one expired. For some reason the new card allow all transactions without pin (payments, tapping). I was shocked. I requested 3 times in the banking app via the secure chat to have this seen to and amended to all and any transactions to request PIN. They have not done this, after 3 weeks. What a useless bank. I will now have to visit the actual branch to have this investigate. What a waste of time and high risk for me. Absolutely terrible.
