Waited for hours for food, some of which did not arrive - terrible service, manager came 45min after being called

The restaurant at the protea hotel in Umhlanga had the most pathetic service at had ever experienced. We waited (while other around us got served) for an hour and half for drinks, which did not arrive all at once for 7 people. The food came through, not all at once, half an hour after that. One of the people waiting for their food did not even receive it after the rest of us had finished eating (it was three samoosas by the way). W e requested several times for the manager, the staff went in different directions looking for the manager who we thought dint exist. Every time we asked for the manager, one waiter would send another waiter to clear our table. Eventually (after about 45 mins) someone whom we were told was the manager came to the table and was quite nonchalant about the whole matter. We were very disappointed and felt disrespected, the service and lack of urgency was quite astonishing. I am surprised that the standard of this hotel restaurant have dropped so substantially.
