The courier guy - Rude delivery personnel

Me and the delivery guy had a misunderstanding in terms of which gate I should collect my package and instead of coming to the gate I was waiting at for him which is not even a five minutes drive he insisted I walk to where he was which for me is a 10 minutes walk. I called him even after he hang up the phone on me several times on me and he was shouting asking me where I while he is the one who insisted I walk all the way across campus again. By the time I arrive at the gate he left with my parcel without informing me.
