2x Dessert with ants

I was at the Kloofzicht Spa with my wife On 01/03/15. The package came with lunch and dessert. My wife's dessert was the Chef's special. It contained wafer, ice cream, strawberries and sauce. After 3-4 spoons my wife saw a swarm of ants inbetween the crushed water. We called the waiter and complained. At that time the chef came out and just went past, giving us a look. The waitor came back with another dish of same dessert, saying that the chef apologizes. Upon examination we discovered that the new dish also had ants. The chef never came out to apologize or find out how he can appease us for this problem. Instead we were told by the lady at the front desk that the head chef examined the dessert and found that there were no ants but pieces of berry. We did'nt see any need to argue the point out. At the end we were refunded R13,00 for the dessert. But that's not the point. The point is my wife injested infested dessert and no senior person came to investigate and apologize to us as customers. Is this how they treat all their customers (skip apology and refund small change)? Need I play the race card here or is there another explanation for the chef's arrogance? Disgruntled!
