Narrative:
Prior to closing the door; the captain asked the ground crew to pull the low pressure air from the airplane. Once the door was closed; we both felt the airplane pressurizing. We tried to get the ground crew's attention to no avail. This included actually getting the attention of one crew member to signal we wanted the hose disconnected or to at least get on the headset so that we could talk. The crew member stared idly back at us; making eye contact; without responding. He eventually turned to walk away. He apparently didn't tell anyone about what he saw; because no one came back to talk and the hose stayed connected. We opened the door to depressurize. The crew eventually disconnected the hose; and we closed the door again. Again we felt the cabin pressurizing. The hose had been disconnected; so we asked the flight attendant to crack the door until we figured out what was wrong. The ground crew had attached the high pressure air without telling us. The packs were still on since we had not begun the air start checklist. We were pressurizing through the packs. I turned the packs off and pressure returned to normal.
