Multiple emails regarding customs charges

On June 26, 2026, I purchased a product shipped via FedEx from Dallas, Texas.

Living in France, I received an email the next day asking me to pay customs duties, which I did.

Shortly after, I received the package—everything was perfect.

A few days later, I received an email invoice from FedEx regarding the tax payment. It clearly stated that I owed nothing further, so there was no issue; it was just a summary.

However, today—July 13, 2026—I received the tax invoice by email again at 1:00 AM! I didn't understand why, so I ignored it, but then this morning at 9:00 AM, I received the exact same email again!

I don't understand why I've received it three times. FedEx only charged me once.
