Greedy and unprofessional service. I called for a chartered service to pick up from SFO. Driver(owner) came 1 hour late after our flight landed. Each time I called he said he is reaching in 5 minutes. After one hour late he appeared, but the van was parked in another floor., he took us to a conspicious location and loaded all our luggage. It was night 9.30 PM, and I was scared to note that there are no vehicles or movements nearby. Then the driver said he has to go upstairs and bring one more customer. I lost my patience, but still thought of adjusting. The driver did not show up in next 30 minutes and I had to call him 3 times in between. When I told him that if we are not going in next 5 minutes , I am going to take another shuttle service. He was almost throwing out our luggage after I told him this. He became very angry and started shouting at me. I was so scared since there was no one nearby. Throughout the journey to my home he was uttering something and I knew he was talking about me to provoke me. But I kept quite, since I wanted to reach home safely. On arrival he demanded 20 dollars extra for luggage. I somehow paid and escaped from him. NEVER NEVER call A1 American shuttle.
