Are your staff qualified?

Earlier this week, 3 sub cards that were previously linked to my main credit card, (and cancelled by me many years ago), just reappeared. I tried calling the number on the back of my card, that was a non starter with the ridiculous voice prompts. Then came secure chat on the app. After 45 minutes and 3 transfers, I gave up on that with no resolution. After all this frustration and wasted time, the mystery cards still appear on my profile. I am convinced that FNB is employing staff who either have insufficient education and/or understanding of banking, or they simply couldn't care less about customer service. It's one, or the other, or perhaps both.
