Dear School,

Thank you for reaching out regarding my visa application materials. I was concerned to hear that they had not been received, as I sent them via courier on April 10th using the SF1439336591158 tracking number.

I am happy to inform you that the materials have been successfully delivered and signed for according to the tracking information provided by the courier service. I apologize for any confusion or inconvenience that this may have caused. Please let me know if there are any further issues or concerns regarding my application.

Thank you for your attention to this matter.

Best regards,

[Your Name]
