I do NOT recommend this service. Not only I lost time and money, my personal information is at risk, and they became unresponsive. The car didn't pick me up on the scheduled day. After 40 minutes or so, I was finally able to get an answer from the Emergency Number provided. They said that City Airport Taxis had sent them an email the day before cancelling the trip. They recommended I hired someone else because they were not able to pick me up. I had to hire someone else on the spot, and pay them a similar amount of money. Two and a half hours after the pick up time, City Airport Taxis sent me an e-mail "confirming" that I had cancelled the trip. All they were able to show as "proof" was a request sent from their own website, with information that only them and the local provider had. I asked them to refund the money I paid for the service they didn't provide, and to delete all my information from their servers since it is obvious to me they are not protecting it as they should. Losing time and money is not fun, but knowing that they have my personal data and somehow criminals were able to get hold of it, is very scary. They said that they are going to investigate. It has been three weeks since their last reply. So far, no refund, and no proof that my information has been deleted.
