Awaiting DACA approval

My wife is awaiting her DACA approval. She submitted on March 10th. This was her first time renewing online - she usually sends out the application by mail, but noticed it’s slightly cheaper doing it online so we went that route. Her DACA and work permit expires next week on the 16th (May). The only update she got was that they received the renewal case and that was about a few days after she submitted. I know everything seems backed up, but is there anything I can suggest her to do? Is there a number to call or something extra to do?
