Be aware of them. I booked through mexican airline website Vivaerobus. When we arrived to Monterrey Mexico, there was NO CAR and nobody there, tried to contact them for 4 hours but nobody answer calls and messages. They charged me $50 USD and did not provide the service. We had to rent another car at Enterprise for 30 USD. Still trying to get my money back after 25 days. Their website does not show contact options maybe because they are a ripoff Very hard to get a response of them, they asked me to send them lot of personal documents, the airline says they can not do anything, call the bank and tried to get a refund but is not possible.
