Gar Hotel Res review: Hotel room booking 1

I applied for a hotel room for the Hilton hotel in Belfast. I made the booking for 23/24 of March and got confirmation for the date of the booking which was 21/22 of March. I tried calling but the phone number did not work. I then emailed them but the email didn’t work. I then called the Hilton and got an answering service in the Philippine’s who were useless and concluded, after 45 minutes, that they couldn’t change the booking!
