Bad customer service at Toyota

I took my car for service at Toyota today. There was a long queue when arrived and I joined the line like all the other clients. when I got to the from of the line, the lady tried to attend to a gentleman that had arrived after me until one of his colleagues told her that I arrived before the gentleman. I left my car there and went to work. Around 13: 00 I call the lady directly to find out how far the service is, she tells me that the car is ready and is the wash bay, I must come at 14: 00. Upon arrival, she explains that the car hasn't been serviced yet, she miscalculated. Not only did I leave early, but their driver also refused to pick me up so I had to ask for a lift from a colleague. This is absolutely unacceptable,
