I wish yelp gave the option to post a review with zero stars, which is what this company deserves. They employ dishonest drivers, do not address incidents and clearly do not care about customer service and should be reported. I was scammed by one of their drivers. He drove me from the Pittsburgh airport to the convention center and first told me that his meter was broken. He pretended that the meter was not working but of course I could not test it myself. He said that it didn't matter though because he knew that a ride from the airport to the convention center would cost $45. I told him that I had been told at the airport's visitors information booth that the ride should cost me $35 (it was 10 am). He said that this information was not correct and he knew because he had been driving a cab for many years. Once we got downtown, he didn't let me swipe my card at the credit card machine mounted in his cab but took my card and swiped it through an attachment in his phone. He didn't give me a printed receipt - although obligated by law to do so, and my card was charged $50. Once I got to the hotel, I asked the person at the reception desk about the fare and he said that I should have been charged ~$35. I contacted Z-trip to report the incident but they never contacted me back.
