Error when making a donation

Hello Community! A few hours ago, a subscriber told me that he has made two different donations to my channel verified by Brave, due to the taste of my content, and he wanted to help me, it should be noted that both donations were 10 BAT each. However, it is important to note that at the time of sending the donation, an unknown error has appeared, then he has checked that his bats have disappeared and I have not been accredited.
What happened to your bats?
Will they be accredited later?
Have you lost your bats?
Can we face a new error?
I hope you can help me with this new problem.
Regards!
