Website sold on flippa. Please help!

I sold my first site on . I started flippa escrow and now I am on this step:
Image here:

1. What does it mean "Transaction has been refunded"?
2. The buyer asked the website transfer by email. Is it safe to send him the website?
3. What if I will send him the website and he opens a dispute that my website is having something wrong, and gets the money back and keeps the website too?

Thank you!
