Bad Service with Bookings

I am very disappointed with your restaurant after being a very big fan previously. I booked a table on Friday 26 March using your booking system for Monday 29 March @18:30 for my fiance's birthday. I had to book at the Alberton branch as the Boksburg branch which is closest to me is not open on a monday. I received a notice that the booking has been submitted. During the day on the 29th I received an email and sms asking me to confirm my booking. I rep**** to the sms as per the instructions to confirm my booking. After driving for almost an hour to the Alberton branch due to traffic and a very bad rain storm, I arrived at a closed restaurant, even though my booking was confirmed and according to their operating times they should have been open. I had to then quickly make another plan, eventually driving all the way back to Benoni to eat at another restaurant where we only arrived after 19:30 and had to have a short evening dinner, spoiling an entire birthday party. Firstly, did no one think to let all the people that made reservations know that the restaurant will be closed for whatever reason? I find this very unprofessional. If no one picked up that I booked a table and the restaurant will be closed, did anyone even look at the bookings to make sure tables will be available for bookings? To make matters worse, on Tuesday 30 March I even received an email asking me to review my service at the Alberton branch. I sent an email using your website on Tuesday morning to get some answers, but to this minute I received no feedback at all. I have sent an message using the website's contact us option and sent a message on facebook, with no response in over a week.
