First Time Renters Beaware

My fiancé and I decided to go to Cape Town and hire a car from Woodford in CT International Airport. When we got there everything went perfect, identified where the car had scratches and dents and off we went. We returned the car 2 days later, Thursday the 27th of June, they viewed the car saying everything was perfect, signed it off and said the deposit will be refunded within 2-3 working days. Agreed and left. We emailed them querying about the refund on Wednesday almost a week after dropping off the car, no response. Emailed all possible addresses we could find on Friday morning, only response we received was to their CT office to sort the issue out. That afternoon we called them and tried to find out what is happening. They contacted head office and we had to call them back to find out what the problem is, they claimed that we damaged the front left of the vehicle. We had signed the vehicle over as no issues were noted and told the deposit will be refunded within 2-3 working days. So they said they'll contact head office again and find out. They called back and said there was a mistake and the money will be refunded. It is almost 2 weeks with no refund. They have caused a huge inconvenience as we have to phone them to find out where our money is and they do not respond to emails, we needed the money used for the deposit.
