ONEair epitomises the bad tradesman. Arranged an appointment using their website after not being able to reach them on their 1300 number, and no one showed up. Called after a few hours of waiting and finally spoke to a person. After arranging a visit later in the day no one turned up again. Called and left a message, no one called back, that was 5 days ago. Do yourself a favour and don't waste your time with ONEair.
