In an already booked, confirmed and paid holiday house without dates of reasons, the date was postponed. Unfortunately we could not on the offered appointment. Therefore we had already booked early (almost a year in advance) No statement of reasons, no apology, no replacement at the desired date ... then came a letter: "We are pleased to inform you that the cancellation you want .. etc.
Again, no apology or explanation
Thank you ! Never again Wolters or Tui
