NO Service at Pricy restaurant Red Ox Upington

Went to Upington and visit the Red Ox steakhouse. They great us very friendly and took us to our table. We waited 20mins with NO service, not even a drink. Many waiters pass our table but nothing. We then stand up and walk out without anybody even notice us. So although they got the Best Restaurant award there prices are unreasonable high and there was NO service.
