Myself and my family travel around the world and yes we do rent cars in various locations, to make our stay on the Czech Republic nicer we decided to rent a car from sixt, after I have secured the booking, I have received a voucher stating that I have paid deposit of €100 and the rest (€389) will be payable at the desk when picking up the car. When I arrived I was told that they had to also freeze excess amount of €1100, this wasn't not written on the voucher, yes I was aware that there is excess, but like in other companies, they simply take €1 security deposit should anything happens to the car. Booking was under my name, Denisa Kaloune but was connected to my husbands flight from Dublin. Since I was unable to over €1600 at the desk I had to wait for my husband to arrive for him to pay it. Before my journey to the airport I received a call from a lady who sits at the sixct desk asking me if I could come earlier as she wants to leave early and doesn't suit her to wait for my husbands flight. Since I was only prepared to €389 at the desk, she wasn't happy because we had to wait for my husbands flight to land. When we arrived at the desk together with my husband later on, she was extremely unhappy and angry, saying that she should have charged us another 850 Czech crowns for waiting for us. What an awful service we received. Unfortunately the worst car rental experience ever.
