I was trying to make a reservation, I thought Im trying via hotel's website but it was Guestreservation site. I did not confirm booking, as the final amount was too high than at the beginning (tax etc) and I cancelled the process. Still My bank account was charged (!!) even though i did not confirmed it, I have not received any email from guestreservation.com. Hotel said they have my reservation (!) and gave me the number from Booking ( I did not make anything via Booking so WT... )... However I cannot do anything because I do not have any email or number from Guestreservation, nothing (again - I stopped during the reservation process and did not make final confirmation, but well MONEY PAID). I cannot manage it and get back my money or anything and it is impossible to call to your service. I see other reviews and the same experience... It is illegal procedure and I've also reported it to the bank and authorities.
