They no longer have costumer service via phone. I would advice to download the regal app since everything you looking for is there.
Regal app or Regmovies.com will be the best sources for movie times. You can try third party sites as well (fandango, movies.com, etc) but I suggest sticking with Regal directly to ensure the times are correct. They have moved the box office inside to the concession stand, meaning there is no one to monitor the phone.
