Bad customer service

On the 25th of Feb myself and 5 of my friends decide to have a girls night out, so we decided to go to the establishment diepkloof. We had a great time but our night ended on a bad not of of their waiters(themba) accused us for not paying a bill that was not ours as it was the 1st time going there. We asked for the manager to solve the matter and the manager gave us such a bad attitude it was like we stupid and didn't know what we were talking about. We felt so embrassed, ashamed and humiliated. If this is how they treat their customers I do not want to return there or recommended anyone to go there.
