They can not be contacted (easily)! (here is a hint!)
We did not receive a confirmation. I thought: perhaps I made a mistake in my email address. Let's contact them. There is no way to contact them on the website. There is a chatbot, but you need the information in the confirmation mail to get this working. The website say in many places that they are very easy to contact, and that their system is even better than calling..... I send them a mail via customerservice in the address Then I received an automatic reply, saying that the mailbox is not maintained. :-( Then I tried their facebook page. Almost the same initial response: we are not available. Miracle: I received an email with a phone number! Dial plus one for the USA, then 9292704046. At the same time, the chat on Facebook responded, saying that they could see in their reservation system that a person of their team received my mail (!) and will be working on it. So I called them (option 5 for other subjects) and the lady on the phone very kindly and very professionally helped me!
