Subject: Request for Proof of Payment

Dear [Recipient's Name],

I hope this message finds you well. We apologize for any inconvenience this may have caused. Our internal team is currently seeking proof of payment for the amounts of 4,500 EUR and 3,800 EUR that were made to CLINICA CORACHAN S.A. Unfortunately, we are unable to locate these payments in our previous records. The only proof we have on file is for a payment of 1,435 EUR sent to the same provider.

We would greatly appreciate your assistance in providing the necessary documentation for the aforementioned amounts at your earliest convenience.

Thank you for your attention to this matter.

Best regards,
[Your Name]
