We're sorry to hear about this situation. All in-game actions such as donations, deletions or general purchases are considered final, given that these require each player to manually confirm the process. Whilst these actions may sometimes be made accidentally, we sadly can't reverse some of those actions due to technical reasons. Some game purchases such as boosters or expansions are not reversible.

With this specific case, I regret to inform you that we were unable to reverse it due to what was explained above.
