Bruh so frustrated

A stranger sent A stranger sent me money through Zelle, and I literally work at a bank, so I called my fraud department and let them know that, hey, I received money from a stranger. It seems most likely fraudulent since they immediately began to text me and call me requesting the funds back, aka you know the most basic scam recently. I asked them if the funds turned out to be fraudulent after their investigation. How long till the funds were out of my account? No answer. So frustrating. Only been a week, but just so frustrating because I obviously don’t want to be put in the negative, so I’m having to subtract the situation now from my funds to get the actual number of what’s in my account. I’d much rather just be able to look and the number be accurate without having to do extra math. And if they could just tell me how long it’s going to take or that they’ll let me know when it’s done being investigated, that would be great too.
