Rosebank Mall Management Does Not reply to Emails

I emailed the general manager Danie De Beer of Rosebank Mall Centre Management, re a shop to lease. However i have had no reply to that email. I then emailed The marketing Manager, Melisandy Davids and no reply to that email. The Rosebank Mall at present has several vacant shops. The vacant shops are perhaps not the result of the current economy but the type of managers that you are employing. I just wanted to bring this to your attention as this non replying of email is just a bad reflection on the management and the Rosebank Mall, as well as loss of income for the Hyprop company and its shareholders.
