The goal is to get more money
We bought a tour to Turkey, paid 50% in March for June. A week later, the tour was asked to "finish off" before the end of the month. Moreover, when booking, there was not a word about such, to put it mildly, "inconvenient" payment terms. Essno expected to pay in full a month before the trip. They said that we can pay off in a month, but not in 2 weeks.
