Appauling service for the hotel group

I would like to share my experience with this hotel group. I made my original booking with them viq booking.com On Black Friday I noted a special, I therefore cancelled my original booking and booked instead via the website. I noted 2 options 1 with the breakfast, R1264.00 the other R1368 bed only. Coming from Durban and also R1264 being cheaper than R1368 I selected that option. When the payment was deducted, I noted R1368 was taken. I immediately called the Pretoria group and alerted them to this. I was told the system takes 10minutes to load booking therefore its not reflecting yet... I was promised a call back, none recieved. I then noted my confirmation email... with no breakfast... i called the pretoria branch. They told me there was nothing they can do, to please contact central reservation. Of which I did via email. A lady Kirstin responded. At that time the deal was still valid so she screenshot the options available and said she will escalate this and would contact me back. All of which never happended. As we got closer to our arrival date I called back... Kirstin could not even remember my query so I had to refresh her memory. So she said eventually she will forward my query to systems and await a response. So the systems claims that I am responsible for the error as that is what I selected. If there was a trchnical error on the day how can I be held responsible for that. Besides on the black friday deal there were many people who had problems yet on Facebook the comments are no longer there. We got to the hotel and raised the problem again, they want proof of the prices, despite me telling them the black friday deal is no longer valid therfore I cannot access yet. Yet Kirstin had the deal screenshot and sent it to systems for my query. Would it make sense now to pay an additional R180 per person for breakfast if what I selected was inclusive. I was charged R1368 it is still approxiatemately R100 more than R1264. And the hotel is not even willing to take this into consideration. I am a paying customer how can I be held responsible for a technical error. Furthermore i reviewed this on Facebook. There was a response that we were offered a room upgrqde... we are at the hotel none of this has come through. Appauling service from such a huge hotel group.
