Customers please stop cussing us out

Im all the way in dairy department I’m trying to do returns before 9:51 two people now have cussed me out for not being able to unlock the glass doors. They press the button, then guy chases me from hardware to crafts to ask me to open it I tell him I don’t have the keys but someone should be on their way. For us the 1000 managers have the keys. Then proceeds to walk away cussing and yelling at his wife. And one time I actually go looking for help what do I get told. Idk who has the keys. By two people. Or I just get ignored. I’ve also been cussed out for certain cookies not being in stock. Please know that not the whole store has keys.
