uber eats hold not reversed

Last month on the 25th i ordered off uber eats and the hold charge went off my card. Later uber eats deducted again because they said that i didn't have enough funds in my account when i did and that the first hold charge would go away after a few days. The second charge did go away but the original hold charge did not reverse into my account and has since dissapeared off my bank statement as pending. Where has that money gone since it did not reverse.
