Poor customer service

For weeks now I have been trying to get an event booking with Mount Grace hotel. It has been an ongoing mission with no end, dealing with so many people at Reservation but none of them have been able to assist me. I have talked to John, Refilwe, Rampasane, another Refilwe (Supervisor), Sharon... This is unbecoming of a hotel that is part of the Southern Sun group.

Can someone from Southern Sun management assist me on this issue?
