I recently had a hotel try to scam me through the official Booking.com messages. Knew my phone number (they also WhatsApp'd me), me booking dates and email address (got more attempts via email). Spoke at length with Booking.com and, despite using them virtually weekly for fifteen years, they did not give a crap and then stopped responding to my emails. All I wanted them to do is get the hotel to refund my booking about two weeks before the date as I no longer felt comfortable staying somewhere that would leak my details.

I will not use them again, just like I do not use Travelodge any more since they repeatedly double-booked my rooms. I feel like, eventually, I'm going to run out of brokers to use. Perhaps I just need to book direct with a handful of hotels.
