Appealing Customer Service

Your food tastes amazing as usual but I just have one glaring problem with your establishment. The customer service seems to be deteriorating at a steady pace. I'm sitting at Ocean Basket as we speak and your waiter Mandla has thought it is appropriate to tell customers (My partner and i) to order their mains with their starters because the kitchen is moving very slowly today. Which would be okay had he not told me that if we dont order and finish our food quickly, management will be unhappy because patrons aren't allowed to dine longer than 30 minutes. After telling him I would like to speak to management directly because I didn't see a sign saying we can't stay longer than 30 minutes, mandla then pointed at some old white man, laughed and said "that's management, good luck with him". I let the incident slide and continued with my evening but further to my ire Mandla has decided to ignore our table for the rest of the evening and serve everyone around us but us. I have resorted to going to the host at the front of the restaurant and asked him to assign us a new waiter as ours has gone MIA (might I add your host didn't believe me when I told him our waiter literally disappeared for an hour).

I'm not going to stop eating at Ocean Basket but I just want your staff to know they are serving human beings with feelings and Mandla has done a good job of ruining my anniversary dinner. Thank you very much.
