711 that’s not open 24/7…?

I have a store near me that randomly decides to lock the doors and say they’re closed whenever they feel like it. I’ve gone and seen it’s a 50/50 chance they actually unlock their doors, basically anytime of the day. The doors are never open, they’re locked constantly. The guy just sits in there doing nothing or just sitting in the back. I see apparently complaints to corporate don’t work and this has been ongoing for YEARS based on the reviews. Can anything be done or is this just part of a broken system
