Terible service and hidden costs

We had a booking to rent a car with First car rental. On landing at George airport we come across a small line at the counter, the only line of all the rental agencies. After about 30 min of waiting we are helped. We are told they don't take cash but can not show us where their policy says that they don't take cash, fair enough. At that time we start noticing the other people complaining how this is the worst service they have ever received and how can it take and hour to get their car. after a vast amount of hidden fees we decide on the spot to cancel. The rude behavior and terrible service of the team and the managers has put me off from ever using them. The amount people that joined us on the spot to hire a car from their competition was staggering, these people stated that they waited for almost 2 hours and still had not gotten their car even though they pre-booked. I would rather walk than hire from First Car Rental
