The service worked fine on the way but on our return we called (as instructed) after we had collected our luggage and left a message on both voicemails (as no one answered the phone), walked to short stay car park, called again 15 mins later and was told that our messages had not been picked up. It was cold and windy and we were travelling with a 2 year old and 3 year old. The car eventually arrived just over 30 mins after our first call, most of which time was spent waiting in cold in car park. The couple who had their car delivered before ours complained if the same thing happening to them. The service does not work if they do not answer the phone or pick up messages. We would rather pay a bit more for a reliable service when travelling with two toddlers.
