I hired a car through Rentalcars.com as agent for Goldcar and opted for the special insurance. When I picked up the car at Malaga, the desk guy took my card which, I thought was to have holding deposit put on it, to find that Goldcar had deducted another special insurance ( around £85.00) I did not find this out until two days into my holiday and called their customer services who said that I could have had the holding deposit put on the card and to go to a local office to revert the payment. I am holiday so why would I want to drive all the way back to Malaga to do that! I have complained beyond belief but Goldcar just do not get it and keep referring to the contract which, was not explained to me at the desk and is also in Spanish! Do not use this company no matter what good deal you think you are seeing online through their agents they use. There is no doubt that you will have money deducted from your account.
