Belittled at Game Eastgate

I went to Game Eastgate trying to purchase a TV since my TV is broken, I had gone to police station to get a permit so I can purchase, yhoooo the attitude from the staff, the manager spoke to me like I was crazy and irrelevant, my heart dropped coz he was standing with another customer and spoke to me like I was some sort of an idiot, I will never ever use game Eastgate in my life I'm just hurt yhooooo
