I called to get a taxi from Yellow Cab only because their phone number is easy to remember. I got a lot of garbage from the so-called customer service agent (operator). Kept wanting to know what the zip code was for my pick-up point. In the noretheast section of San Antonio the zip code doesn't matter. They should know the city as well if not better than the drivers do. I hope that I never have such an opportunity to utilize this service ever again. VERY RUDE CUSTOMER SERVICE!!!!!!!!!
