No response and No feedback

I have sent an email to Kitchen Bar design quarter in sandton 2 weeks ago enquiring about a booking. Till date i have not received and feedback, I tried calling them everyday with the number provided on their website, all it does is just ring with no answer. All I am requesting is feedback to availability of the restaurant for a specific date, and how many people it will be able to accommodate. I don't think I am asking for too much, just a response.<br> <br> The contact number on record, please do update as well.
