Trash customer service!!! Don’t go there !

Very bad experience from this Restuarant , after spending R4217.40 on the bill , this Restuarant kept us hostage for 3+ hours because of their own faulty card machine . The payment went off on our side but on their side the payment was unsuccessful… it’s been hours we still sitting at the Restuarant , after 3 hours . They are failing to resolve the issue with their bank and our bank has confirmed that the amount went off . My friend even drove off and they made the police follow her , harras her , take her car and bring her back to the restaurant . 3 hours later the issue was not resolved !!! Very very bad service & management, the management have no idea what they are doing besides speaking badly about us to their fellow colleagues in the toilets , one manager Nomvula told her colleagues that since we have degrees we should pay the amount again !!! Never ever setting foot at this restaurant!
