Complaint Review: Dulles Airport Limo Service

I prepaid for a car to pick me up from Dulles Airport and take me to an address in Virginia. When the car did not show, I called the company. They told me the car had broken down and they could not get me a timely replacement. 

They told me to Uber and that I would get a full refund. That did not happen.  I disputed it with my credit card company, and Dulles Airport Limo Service produced the prepaid receipt as evidence that they did provide the service.

Now they are not responding to calls and emails.  I think this company is a scam.
