They dont offer a Latter of Guarantee, so there is no way we can say 100% for sure that the first address is theirs. So, I assume you are 100% that the first address (3Fz3...) came from their website, right? Did you double check the address you copy/pasted when sending the transaction?

Yes, I'm pretty sure that the address I use is exactly the same address shown on the page.
I scanned the qrcode when sending the transaction, and I double checked the address in the qrcode.
The address in the qrcode and the address on the website is exactly the same.

The deposit UTXO has been spend after 27 confirmations. That indicates that they do have the private key of the address.
