However, the flat is closed to the public and the company does not disclose a real Israeli telephone number.

We saw in the homepage that the company uses an American PO box and claims it to be an American University; all mail is actually processed in Israel or, more often, by remote workers in Nigeria, India etc. Also, the US telephone number is actually a virtual number with throwaway voicemails; therefore, it is completely useless to contact them by phone.
