@Marko2504 I would just keep pressing the issue with Uphold support. That looks like a stock reply and that really didn’t answer your question. Let them know you are asking about the BAT that is already in your Uphold account. Ask Uphold support what your options are.
Steeven posted in a different topic that Uphold was sending out emails to affected customers. Did you receive anything from Uphold?
And this post discussed the issue and had some options you might consider.
