I managed to hit my bank's internal security team this one time. Pretty cool to chat to them at the time although they mentioned as little as humanly possible about their policies for obvious reasons :)
My account basically got itself into an invalid state where I couldn't verify using my pin or log in online. Must have slipped through the cracks in business logic somewhere because I combined credit and debit onto a single card and created a 6 number PIN. Called customer service, got escalated to higher level, then a few hours later called by someone from the internal team.. which worried me slightly.. but was fine in the end.
