Disgusting service

I don't know exactly how to describe the level of disrespect and unprofessionalism the management and owner gave us on a day we supposed to be celebrating my anniversary with my 7 mouths pregnant wife. I bought vouchers for 2 through hyperli to dine @ Zen Fusion for a 3 course meal , on 24/09 10h38 am, I phone through and made a table booking for 2 for that evening 5:30pm .3:54pm we received a call from them to confirm if we are still coming and i confirmed yes . We drove from horizon Roodepoort to Emperors Palace ,we were exactly on time. When we arrived we were greeted by the owner on the man desk , we explained we had made a booking ,She explained inside they are hosting a function if we don't mind dinning on the outside of which we didn't mind and then we were given a waitress to sit us down .She then was supposed to come back with a drinks menu of which a manager by the name of King came back to us to explain that is seems that the wont be able to serve us because of the function about to take place so we need to come back some other day or later after the function they are hosting after 10pm .What sickens me is the story changed to they cant find our booking , we presented the evidence of calls to and from them regarding the booking, they agreed someone had called us but they don't know who spoke to . The owner failed to take ownership of the mater , in fact She was dismissing us ,we were pestering her and she had better things to do. She never took any initiative to see to it that we leave happy customers , she didn't care. I am disgusted of the service and hugely disappointed in the level of disrespect and disregard of our basic consumer right. The fact is the service we experienced is appalling and disgusting and would never dream to ever dine in this place.
