I bought 4 tickets (two one-way, two return) on 4 different airlines using this service. One of the flights was canceled by the airline and, in Due to the fact that I did not have the opportunity to reschedule flights, I wrote an application to the operator aviasales (it is kiwi.com) for a refund.

When I tried to To get through, the answering machine at first said that telephone communication was only possible 14 days before the flight, and when the 14 days came just the call is dropped. So, communication with them is only through the website, where they just write off that they are working on this issue.
Retrieved from I wrote letters to the airlines where the tickets were purchased to see if they even had a refund application. 3 responded, to communicate with the operator where I bought the tickets, and the airline that canceled the flight, UTAIR, said that back in December it returned the money funds. I wrote to aviasales about this, to which I was told that even if my money was returned to them, they first calculate on the statements of other clients that were filed before me, that is, they cover their debt with my money.
