I received a WhatsApp (which isn't unusual on booking - often the accomodation will message)
From a business account, with correct logo and address of hotel asking if I needed information on parking or public transport.
The message addressed me by my name that I used on booking, which had a typo in it (new phone autocorrected my name) had the dates I was staying and that I'd booked via booking.
I clicked parking and it replied with an AI response of the local car parks etc. didn't think any more of it
Then I got a message a day later from same WA, saying there was a problem with my payment, booking would be cancelled and I needed to log in, and of course they provided a link.
Thankfully I immediately thought scam and contacted booking.com, they confirmed it wasn't from them or the hosts and that I should just block the number, with an attitude of well these things happen.
They didn't want to look into it, or have the details forwarded or care that my details had been harvested.
This wasn't a vague fishing scam, they knew all the details, the dates and my incorrect name so somewhere at booking or the website they have had a data breach and they don't GAF.
AIBU to expect a major website to care about information breaches?
