There is no solution to that issue other then either wait or delete. The delete link is "hidden" near the filename on the assets description. It can be very easily oversean.

No one here knows whether they will ever be approved. I recently had some assets reviewed that waited for nearly a year. The only thing you can do is to delete and resubmit and hope they catch the attention of the review team this time.
