FAQ Settling in France

I have a French bank account in France. In a restoration dispute, two cheques to seperate suppliers ‘bounced’. I have paid suppliers the full amount, one by bank transfer and the other in cash. I did not get receipts and neither supplier has responded when I asked them to confirm they have been paid. How long will I have to wait before these bad payments are wiped from my record and will I still need to pay timbre fiscal to the bank?
