Bad service

Salt Rock Hotel was recommended by the apartment owner where we were holidaying. Four of us went there for dinner on Saturday 30th of October. I ordered a medium-rare steak. I was served with a well-done steak. The waiter took my meal back to the kitchen and brought back the same steak, saying that they could not change it as he had made a mistake. I refused to accept the meal and asked to see the manager. The waiter took the meal and, 20 minutes later arrived with a medium-rare steak. The manager was nowhere to be seen. I ate my meal alone as the rest of our group had finished eating. Service was terrible and not even an acknowledgement that they messed up!
