Reserved a cab about 12 hours in advance for a ride to the airport.  No call back as mentioned on the web site.  This was the second time I did not receive a call back. \nCalled at 6:48am on 6/29 to see if we could get our 7:10 cab early to the airport.  I was told that our driver will be calling.   At 7:07, after no call or text,  I called back to see if our driver was even going to be on time.   This time I was told the driver would be 5 minutes late.  At 7:17, the driver called to say he would another 20 minutes.  Huge failure on the part of your business.   I will no longer be using clean air cab and will be reporting this experience with others.
