We ordered a taxis to pick us up and take us to the airport from JFK airport. On both occasions the taxi did not turn up. We emailed this company twice on holiday and subsequent complaints from July have been completely ignored. When we checked the taxi company in New York they had booked for us it had one star!
Do not use this company. Their customer service is non existent. Please do not respond and tell me to email you. I have already and you just ignore me !!
