Unhappy client with Agoda

I've made a booking with Gardenia Boutique hotel in Johannesburg yesterday when they send a confirmation I noticed that it is not what I requested. The number of guests was incorrect also the type of room they allocated. I then immediately contacted them to assist me and also communicated with the hotel Tryron is their reference. He was not willing to assist at all. I didn't want to cancel the booking but they can't expect me to book a separate room from my kids who are still babies in this demonic society it would be irresponsible of me to throw my kids to the wolves. They will not even feel safe left alone. So I am charged for cancelation and am still taking the trip I still need accommodation. This is a total reap off. Online bookings chances are I will still stumble on the same booking site. Am not happy at all.
