Bad. I had to take my car to get fixed and my new puppy needed food, so I called clean air cab to take me to pet co. I was quoted 25 minutes maximum and 30 minutes later I called back to see where my can was because it hadn't arrived nor did I get a call with an ETA. The person I spoke with said they would have the driver contact me. I called back again because I hadn't recieved a call. The girl on the phone told me the driver tried to call and since I didn't answer he left. I had no missed calls and when I asked them to verify my number to see if my contact information was correct, it was all right. Hmm? So I asked another cab to be sent out and got quoted another 30 minutes. This is not the first time this has happened either. I only use clean air because they're cheap, but if you need to be somewhere on time, stick to discount cab, they're pretty realiable and the fare is decent. You'll save yourself a lot of hassle.
