When I was in a lot of debt, banks outsourced collections agency called many times on a private number and wanted me to verify myself before they would verify themselves. No. Bank denied they would do that but that was lies. They couldn’t even admit to trying to get in contact with me. Collections agency couldn’t even play the theoretically game of maybe there’s a certain someone out there, who knows who, who hasn’t paid off a credit card, maybe this certain someone would want to consider going into his bank and having a chat but that’s not for me to say ah capishe? I’ve got a rock you’ve got a sword how are we gonna play this out? Good times haha
