Left stranded by Umhlanga Inn & Booking.com

We made a reservation through Booking.com for Umhlanga Inn. The address given was incorrect and none of the telephone numbers listed could be contacted. My wife and 10 year old son, after searching for the venue for almost 2 hours were left stranded. Booking.com have made no attempt to resolve and Umhlanga Inn cannot be contacted. Do not trust either Umhlanga Inn of Booking.com.
