Visiting this place twice a year, already had like 4 vacations there. We accidentally ordered online through booking and they charged me the full amount even though I cancelled like 2 minutes after the accured mistake. I called this morning again to cancel my charge, I faced tony ( ) over the phone, which was not helpful at all. Said that there is no manager that can help me and that he cannot cancel my charge. This is rediculosly funny to do such thing over a honest mistake and especially when we spending thousands of dollars there every year. I'm shocked!
