Very Disappointed

Very Disappointed in Travelstart! I will not recommend to book a car via Travelstart! I booked and paid a car via Travelstart for our honeymoon vacation. When I got to the agent to collect the car the agent said that there was no car for us and the booking was cancelled! Okay so now I call Travelstart just to find out that I have to deal with a third party "Cartrawler" from the UK! It is exactly a month today and still have not received a refund! I just spoke to a Travelstart lady who was very rude! She said she can not do anything and hanged up the phone in my ear. So disappointed in Travelstart, as I trusted them when I made the booking for our Honeymoon. So what do I do now? I do not want to loose all of the money I paid, for a service that I did not use :-(
