Terrible Service

My friends and I went to Radisson Blu Gautrain Hotel for drinks on Friday evening 11 January 2019. The service was terrible. We were sitting at the roof top near the swimming pool. We arrived there at 17:27. Firstly, no one attended to us when we arrived, we had to go call someone to come take our orders. After we had placed the orders, we waited for so long we had to call the waitress to ask what's happening with the drinks. Some of my friends ordered beer and soft drinks, myself and other two friends ordered ****tails. The beer and the soft drinks finally came after we complained but we still had to wait for the ****tails. The ****tails finally arrived at 18:22 but when they came they were virgin ****tails - we did not order virgin ****tails so we had to wait some more. When we complained to our waitress Patricia, she gave us an attitude. Another lady brought the ****tails after a few minutes. No one ever came back to our table to check if we wanted to order more drinks or food. We wanted to order food as well but the service was so bad we decided to leave. We had to go to the counter to get our bill to pay because no one was attending our table. The place is nice but the attitude of the waitresses was so bad.
