BTC payment to Amex via BitcoinWell shows “failed” but Trezor says it was sent — what happened to the BTC?

I’m hoping someone can help because I’m honestly panicking.

On March 5, I sent a BTC payment using my Trezor to a Pay Bill address provided by Bitcoin Well to pay my Amex card.

A week later I noticed the transaction shows as failed, but when I log into my Trezor wallet it shows the BTC as sent.

Now I’m really confused and worried.

So I’m trying to understand:

• If the transaction failed, where did the BTC go?
• Why would my wallet show the BTC as sent?
• Could the BTC still be stuck somewhere or pending?
• Would the BTC normally return to my wallet, or does Bitcoin Well have it?

Has anyone experienced this with Bitcoin Well bill pay or with a Trezor transaction showing sent but failed?

I’ve contacted support but haven’t heard back yet and I’m stressing about where the BTC might be.
