Avoid booking via Kiwi - I do not recommend this platform! I booked a flight via Kiwi, paid and got a confirmation. In the middle of the night I was informed by email that due to technical issues the flight couldn't be booked and that I have the option to be refunded via creditcard (chosen payment-method) or with Kiwi-vouchers, however it was not possible to choose the first option in the form shared. When I was informed that I got refunded with Kiwi-vouchers I contacted the Customer-centre and they asked me to proof that it was not possible to choose that option otherwise they couldn't do anything and they apologized for technical issues. It is obvious that I can't proof a technical issue from their side, thus I am stuck with their voucher. In the conversation with the customer-service they aknowledged the "failure/technical issue" from their side, and were sorry for my frustration yet still nothing that could be done.
