Had precooked a taxi the night before for a pick up early in the morning for Ottawa Airport. Blue Line taxi B518 was sent but never showed up. Phone call to Blue Line for assistance, no help at all - always said taxi is coming. Tried to track the taxi. Worried that we might miss our flight, I phoned another taxi company but was told Blueline Taxi services the airport. Phoned Blueline Taxi again and ordered for another cab, within 2 mins it arrived. Cab B518 no show then sends text I’ve arrived.
