Please do not use Meet Up and Park at Heathrow Terminal 3. On arrival back to UK as requested we called company letting them know we had collected baggage, we were advised that it would take between 20 - 30 mins for our car to arrive in car park. After 30 mins waiting, I approached representative as car had not arrived. This person was extremely rude and aggressive and would not answer my questions. I contacted main number to speak with manager, promised call back - never happened. It took over 50 mins for car to arrive. I was not the only customer who was experiencing this service.
