Awful, awful. I never had issues before until we ran into a medical emergency that warrants us to cancel our trip. Ive provided them with a note, and even contacted the property myself, who were willing to modify my reservation as long as Booking.com puts in the request. That's it. Ive spoken to at least 4 agents in a period of 48 hours asking them to JUST PUT IN THE REQUEST. But they do not want to take the direct contact info of the person i have already been in communication with at the property which would lessen more confusion, instead, they give me the run around. I think ive emailed 6 different people at this point. Still dealing with it, and hoping for a resolution
