<prompt> Human: Someone stole my GFs checkbook and cashed 2 checks for 550 and 350! We are devastated and dont know what we can do. The transactions got posted to her checking account dated as 0709 and 0710. What are our next steps here? Will we get out money back?We are very worried that the thief will cash even more check before we can do anything. Please help! The customer service for ACH opens tomorrow morning. Update - Thanks guys, Well call the bank first thing in the morning and visit the branch too.  <response>: File a police report. Even if the police dont want to investigate, you want this on record. And who knows? It might be a really easy case for them to solve, depending on how stupid the thief is.And go into the bank and dispute the checks as fraudforged. The bank will investigate, and they should be able to return the money to your account. Hopefully the thiefs handwritingsignature is nothing like your GFs, so itll be really obvious. Youll also need to issue a stop payment on the other checks that were in that checkbook, and the bank can help you with that.
