Awful customer service from store manager

Went to Game for collection. Upon arrival "KG & Lee" had an interesting conversation in front of me and when I started asking questions about their sales process that's when Lee left the sales counter and wouldn't come back to give clarity instead KG decided to call trevor. Store manager "trevor hoyte", what a nightmare it was dealing with him. All I needed was for "lee" to explain something to me regarding their sales process. Trevor wanted me to prove what I'm talking about but he won't let me do that by calling Lee to come explain their sales process. He refused to call "lee" and instead accused me of harrassing "his staff" - as if he owns them. How can I harass someone who is hiding at the back office? Trevor was rude, unprofessional and uncooperative. He refused to give me his regional managers contact details and arrogantly told me to "google it", saying there's no other manager that I can talk to besides himself. I wonder if customers mean anything to this guy.
