Returning a rental is no joke.
Essa, when I arrived at CT Intnl., the service was perfect and the car too. I decided there and then to change to Woodford for all future rentals. Returning the car was the opposite experience. With a load of luggage and a physically challenged wife, I found myself in a narrow lane with a car parked in front of me and no one in sight.  I waited 10 minutes for someone to turn up and when that did not happen, I had to leave my wife in the car to be harassed by an airport porter. I had to walk all the way to your main office report it and walk back again.                                                                                 Someone appeared at the kiosk but they still wanted to offload me with all the luggage and my wife that can hardly walk 20 metres, miles from the airport.          By now we were running late for our flight, the weather was deteriorating and I was ready to go to social media and blast Woodford for complete lack of customer care.
At that point in time the day was saved by your employee Clifford who appeared on the scene. He jumped into action, removed the !@#*! car that blocked the lane and drove us to departures. He saved you company's reputation.
You have to do something about the system of returning cars. It is not good and I am surprised that you do not realise that. I understand that you are subject to the airport authorities whims and rules but it does not work.
