BAD SERVICE AND BAD CAR

I hired a car. Battery went flat. Call road assistance after the second time with the same problem. After hour road assistance came and jumpstart the car. I phone and log a complain because I was paying for proper car that is in running condition (suppose to be). Port Elizabeth airport office told me that a replacement car will be sent to me. After two hours I phone them again. Receive news that the replacement car will be sent to me the next morning. A still have to pay for the use of a car that is not in a running condition. I have also phone the national centre to log my complain with them. They told me that PE will be in contact with me. After few days still no contact and still no response from first car hire. The service received is really bad!!! What make this worse is that this service is promote by FLY SAFAIR. 15 percent discount. Rather make use of other cat rentals and pay for proper cars in running conditions and better services!!!
