Dear Sir/Madam, I am Ali Vahidi (vahidi.[protected]@gmail.com). I searched a flight ticket in Kayak.com on 10 July 2021. I set the price result to be shown in euro then I chosed the cheaper one. I forwarded to agancies website (Travel2be.com) and I did the payment. Whole the price until payment was in Euro. After the payment I recieved the invoice and the price was in pound. So I payed about 100 euro more because of currency change fee. I explained my experience to Kayak and they answered me with things that were not helpful. I want to say, there is no information about currency change in whole procedure of searching and buying a ticket not only in Kayak.com but also in Travel2be.com. And it is nonsense to search in euro and pay in another currency. At least they should mention it. I believe Kayak.com is responsible for my problem because they should give enough information about the searching result and also they should evaluate competence of corresponding agencies. Finally, I am disappointed and feel like a person whose money was stolen. Regards, A. Vahidi
