Story: After being burned multiple times via booking.com and other third party sites, I tried to book directly with the hotel. I was planning a last minute trip with multiple stops and so i just booked a hotel and forgot about it thinking that once I arrive in Ireland i'll look up the details. There was this hotel in Ireland that accepted my booking, charged my damn card the day after the first night, but never actually sent me any confirmation or any emails. When I arrived I didn't remember whatever stupid quaint name the hotel was because I had booked about two weeks prior. I guess this was my bad because I was used to a hotel freaking emailing you something when you book.
When I arrived I was desperately trying to search for any indication that I made the booking and my credit card didn't even have a record. I gave up and ended up booking elsewhere.
Then all of a sudden after the first night I got charged. I was absolutely livid. I demanded an explanation. Turns out what happened was then when I first tried to book, their email form had an issue where my broswers autocomplete added the name of my email after the .com so it was email@gmail.comemail. The site rejected it and I realized the error. I hadn't entered my credit card info so I thought I was fine. I resubmitted it with the correct email and then entered my credit card info. Booking was accepted.....turns out their system somehow retained the first email and send out the confirmation to that email and they had no indication that the email bounced until the person looked up the issue AFTER they had charged me. Whats even crazier is that on the second day they emailed me first asking where I was before I could reach out to them! So they had the correct email in their records but their internal billing system captured the wrong email!
You can't win either way it seems! Fortunately I had a long email chain where they admitted their system never sent out a confirmation. my credit card company sided with me in this regard when I attempted a chargeback.
