4 hours to finally get a full meal

I was extremely disappointed by the customer service that 4 of my friends & I received last night at the John Dory's in Queensburgh, Durban. We arrived at 18:00 only to wait 20 minutes to get a table. Once we got a table we ordered sushi as well as prawns & hake. The prawns and hake arrived within 15 minutes from the time the order was placed however the sushi was only received 2 hours later. We constantly followed up with our waitress, Bongi with no joy. Eventually we received a third of our sushi order from one of the managers, Dumi. After constantly following up with Dumi, we were told by him that only a portion of our sushi order was ready and that we will have to wait longer for the rest of the order. Thereafter, we approached another manager, Julian in hope of receiving some luck with getting our order as it was going on about 21:00 and needed to get home. We also explained to Julian that other patrons that came after us received their sushi before us. Julian was of no help. Finally we had to re-place our order with Bongi and received it at 22:00. 4 hours to receive a meal that's appalling considering my husband & I are regular patrons of JD at Queensburgh.
