I booked a stay at the Bellagio with Booking.com and although the T&Cs clearly states that all fees are covered, the hotel charged me resort fees and taxes on top. This was 7 months ago and I am still trying to get the fees back from Booking.com or the Bellagio. The Booking.com customer service tried to stall my request by asking for more and more detailed receipts, which the Bellagio refused to provide. Now, after 7 months of calls and emails in the double digits, Booking is claiming that I can't get my money back, because I used their Booking base" tariff and did not opt for their premium service. Needless to say that this is not correct and the T&Cs still apply in my case. Conclusion: Booking is a total scam and I will pursue legal action.
