I have recently made a reservation to the AC Hotel by Marriott Stockholm Ulriksdal for March 25th to 27th.The debit to my credit card was done, but then, the webpage indicated that the room wasn't booked because no more rooms were available.I've called there support line, which goes to an automated script, which was unable to resolve.Tried to send a request to their Contact Us form, without success as well.Lastly sent an email to the customercare[at]guestreservations.com, which I'm still waiting for a response.
