They get half a star because the fleet is in good condition.
I required a taxi with a baby seat to go to the airport, so I booked over a day in advance. The booking was taken, no arguments...they just didn't show up and didn't bother to call to say they didn't have a cab to send. So we were waiting outside our house in the rain with a one year old when they were due to arrive. Ten minutes later, when they hadn't appeared, we called to make sure the driver was on his way. They told us they didn't currently have a free driver, so we asked when we could expect him to arrive and were told they didn't know & couldn't guarantee that a cab would come at all. I asked what the point was in taking bookings and they said you can make a booking for your own peace of mind (?!) but that they couldn't guarantee that they would have a driver when the time came around!
We almost missed our plane, it was just lucky that we had initially 'booked' with plenty of time to spare, because by the time we'd called another company and been picked up it was cutting it very fine. A totally, utterly undependable service. I can only assume that they give preference to large group bookings because they can charge more for it.
Poor and stressful, to say the least.
After almost an hours wait at Sydney International Airport - I called LimeTaxis, only to be told that they did not do pick ups from the airport. Why was I allowed to prebook online? I asked the person on the other end. I was told they were not sure, and they'd let their supervisor know of the concern and that waiting for almost an hour was truly unacceptable. Yes, I agreed - it was. I went on to tell them I'd been travelling for over 24hours and that they should probably send over a taxi right away. After a series of "ums", "ahs" and "likes" I was told they'd refer my case to their supervisor. Was I picked up? No. A truly disappointing service.
