Then later, our company set up the system with the bank. All cheques data went to the bank at first. When someone tries to cash the check, the check will be checked by the bank system compared to our data. But the bank charged the fee for this service. For small companies, you don't need to set up this service, but at least you need to access your bank account every day to view all the cheques cashed. Normally bank can refund the cheques cashed within 2-3 days. I think it will be difficult to get the money back from the bank for your situation. Good luck!
