Terrible/no service

Wanted to take my kids for some sandwiches but been waiting for almost 20 minutes before one of the HOSTESSES (not even a waiter) took my order. She told me the manger will come to me but he/she never did. Waiter didn't even introduce himself. Was sitting @ table number 25. Waited another 15 minutes for 2 hot chocolates to arrive, and another 10 minutes for a pot of rooibos tea to arrive (without milk - luckily I don't take milk but point is it didn't come with the tea). Then waited for another 10 minutes for 1 plain toasted cheese (kiddies) sandwich to come after I ordered 2, then I had to wait another almost 20 minutes for the other sandwich to come. People that ordered after us got their food almost 15 minutes before us. Not once did the waiter or the manager apologised for the bad service. Bottomline, we waited 20 minutes for our order to be taken. 15 - 25 minutes for drinks to arrive and 35 - 55 minutes for 2 easy sandwiches to arrive. We were seated @ table 25 & I got the waiter name from the bill. It's Itayi. Had to ask numerous times for take away bowel, eventually got someone else to bring me one. Service overall was very poor and numerous tables had issues.
