Stay away (rogue company/criminals)!
We booked a hotel in buenos aires which turned out to be a total disaster! Firstly, this portal has no hotline number; secondly, emails are only answered after days; and when it comes to the reimbursement of costs, you get no answer at all. DOWNRIGHT CRIMINALS! Update (after response of Billabook to the original review above): since their legal/public relations department is very responsive in regards to open criticism (by requesting further details to the booking), we kindly advise them to take a look in the claims and open issues of their support team ... Update2 (after 2 months of writing emails to their support team): still no satisfying answers and worst of all, no refund issued. THOSE ARE CRIMINALS (see other reviews)!!
