NS’s latest promotional campaign, Wintercity, mistakenly sent out winning notifications for a private chef dinner to around 6,000 participants instead of just one. The technical error has led to frustration among users on NS’s traveler forum, who were expecting a luxury experience. The transportation company has acknowledged the mistake, vowed to ensure better checks, and continues with their Wintercity campaign despite the backlash. Previous errors in promotional communications have also been reported, raising questions about NS’s handling of such events.
