This type of thing seems to be happening here in the US quite often this past few months also. I have tried booking a hotel and renting a car through two different companies and both times I have gotten an error when I tried to pay for the items with a credit card. However I was not billed for either one. It seems that the credit card people may be putting some type of security system with regards to booking things on line and that is causing these error messages to pop up giving you the impression that the system has failed when if fact the transaction was completed. In my case nothing was completed on line, however when I called direct to the companies there was no problem getting booked.
