If I could give minus star I would Arrived at the site ,very badly signposted, 2 guys took us to Stansted in a car, no masks worn . On our return we rang them , left message walked to blue area as instructed, rang again was told to go back to airport as they only had one car and were very busy, they would ring us. No call and several calls from us later they said they would meet us in our car . We had been waiting for 1 1/2 hours and had travelled for 12 hours . Went to area C but no car ,more calls and he was parked over road. Could hardly speak English but mumbled sorry,walked off ,we had to pay £7 to exit airport! We could have booked parking at airport for same money!
