I would like to inform you with this email that you customer service representative who explained this sum in his own words was that this sum should be withheld until the rental period is over and refunded when the rental ends. It is possible to lie on delivery and get a signature on delivery I have never heard of. I have my wife and daughter who were with me and heard the conversation and can confirm it. I clearly said that I have travel insurance that covers a car as well. But the sum of 223 euros was withheld according to their customer service representative as security and paid back at the time of submission. It's trickery to get your signature and change it to something else
