The tour was sent by Ilona Antonov's 'Katrin-Tour' company, through Irina's 'Pylon'! Traveler scam!
We bought a tour to Montenegro, from the travel agency "Katrin-tour" (Kyiv). The manager who recommended the hotel booked and sold the tour - Antonova Ilona (in the contract she is listed as a director). The tour was bought for two weeks, the company was 5 people. The day before departure, we got a call that we could pick up the documents, then we found out that the flight was being postponed, from 10 am to 6 pm, so we actually lost 2 days of vacation.
