little feeback resulting on lose of booking

on the 3rd January I looked at booking a hotel in capetown using my vitality on kalulas website. I found that the vitality discount was not accurate when I went to the actual hotels website. I send vitally an email wih the screen shots as proof. i recieved an email saying they were working on it. i only received a call on the 20th Jan. I sent then over 5 emails asking for feedback. since then the room I booked has book booked up. because of the delay I do not have the original booking I requested. now there is only one room available but it is more expensive. the result I the delayed feedback resulted in me not getting my booking. I request that the available room be booked at the original price requested. I called through yesterday and they said a travel manager would call me back this has not happened. I have already booked my flight so I need to sort this out asap.
