With the present I am testifying to my negative experience with Sixt car rental. I booked a car through website with pick up and delivery in Amsterdam Schiphol, 10 days car rental of medium category type Kia Stonic or similar with manual transmission. The total booking for the 10 days was 243.00 € I check in others generics rent cars sites and I find the same price, so I decide to book directly from sixt. First of all I want say that I work with Corporate Travel (I am Sales&Account Manager of the corporate market in the north-east of Italy) and for many years I'd rental car for work issues to then also be able to advise any suppliers to my Corporate customers who travel for Business. Arriving at the Sixt desk in Schiphol I find an attendant asking me a series of personal questions, totally inappropriate. After that he proposes me a higher category car with automatic transmission because the one I booked (and confirmed! ) is not available. I say yes to him provided that the price is obviously the same. He confirms to me that it is the same price and I accept thanking him for the upgrade granted. *****He asks me what insurance I want and I confirm that as confirmed online, I do not want insurance and additional options compared to what was previously confirmed. He explains that in the total on the screen I will see the price of the deposit that will be blocked for the rental days and subsequently blocked and in 'trust' I proceed to the digital signature of the contract****** When I return the car I find that the total I have to pay is exactly double that when confirmed and they tell me that it is an additional insurance that I chose during check in at the desk. Confused, I start checking contracts, confirmations and receipts in my possession and I actually read that I was given additional insurance never required, sold to me without my consent when delivering cars and passing it off as the deposit. I Rental cars for many years with other historical and international suppliers and nothing so unpleasant has ever happened to me. I have never had to pay 1 euro more than when confirmed and pre-paid online. I informed myself for days and found many, unfortunately, reviews where cases equal to mine are witnessed. Dealing with sales in the same sector, I can with certainty say that ancommercial omission sale of information and clarity has been made and that it can probably be a 'legalized scam' Testifying to this I have the person who was with me who witnessed the conversation and all the confirmation vouchers that report the total of 243.00 confirmed at the time of booking and subsequently at check-in. I look forward to your prompt response on this matter. As recommended by Trading Standards, I would like to keep a complete record of my case, so please reply to this email address. By virtue of the fact that my job is to suggest the various suppliers to my customers who travel for Business, but above all, by virtue of a professional and clear work ethic. I think it is shameful what has happened. Yours faithfully, Gloria Tommasi Travel & Business Development Consultant Area Manager North - East Mobile: +[protected] e-mail [protected]@gmail.com
