I, too, got the voucher from LivingSocial. As of this writing, I've been trying to contact Xavier Limo for about a week to set up a R/T to the airport. When I first started calling I got a message that their voicemail was full. I finally got through and left a message. No one called me back. I went online and submitted an email form to make a reservation. No one contacted me. I left another message today and quite honestly, I'm not expecting a response. Our trip starts on Jan. 21, so I really needed to get this locked in. It's not looking like that will happen. I'll update if anything changes. Quite a disappointment!
